Reminding peer reviewers of reporting guideline items to improve completeness in published articles: primary results of 2 randomized trials

Importance:  Numerous studies have shown that adherence to reporting guidelines is suboptimal. Objective:  To evaluate whether asking peer reviewers to check if specific reporting guideline items were adequately reported would improve adherence to reporting guidelines in published articles. Design, Setting, and Participants:  Two parallel-group, superiority randomized trials were performed using manuscripts submitted to 7 biomedical journals (5 from the BMJ Publishing Group and 2 from the Public Library of Science) as the unit of randomization, with peer reviewers allocated to the intervention or control group. Interventions:  The first trial (CONSORT-PR) focused on manuscripts that presented randomized clinical trial (RCT) results and reported following the Consolidated Standards of Reporting Trials (CONSORT) guideline, and the second trial (SPIRIT-PR) focused on manuscripts that presented RCT protocols and reported following the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guideline. The CONSORT-PR trial included manuscripts that described RCT primary results (submitted July 2019 to July 2021). The SPIRIT-PR trial included manuscripts that contained RCT protocols (submitted June 2020 to May 2021). Manuscripts in both trials were randomized (1:1) to the intervention or control group; the control group received usual journal practice. In the intervention group of both trials, peer reviewers received an email from the journal that asked them to check whether the 10 most important and poorly reported CONSORT (for CONSORT-PR) or SPIRIT (for SPIRIT-PR) items were adequately reported in the manuscript. Peer reviewers and authors were not informed of the purpose of the study, and outcome assessors were blinded. Main Outcomes and Measures:  The difference in the mean proportion of adequately reported 10 CONSORT or SPIRIT items between the intervention and control groups in published articles. Results:  In the CONSORT-PR trial, 510 manuscripts were randomized. Of those, 243 were published (122 in the intervention group and 121 in the control group). A mean proportion of 69.3% (95% CI, 66.0%-72.7%) of the 10 CONSORT items were adequately reported in the intervention group and 66.6% (95% CI, 62.5%-70.7%) in the control group (mean difference, 2.7%; 95% CI, −2.6% to 8.0%). In the SPIRIT-PR trial, of the 244 randomized manuscripts, 178 were published (90 in the intervention group and 88 in the control group). A mean proportion of 46.1% (95% CI, 41.8%-50.4%) of the 10 SPIRIT items were adequately reported in the intervention group and 45.6% (95% CI, 41.7% to 49.4%) in the control group (mean difference, 0.5%; 95% CI, −5.2% to 6.3%). Conclusions and Relevance:  These 2 randomized trials found that it was not useful to implement the tested intervention to increase reporting completeness in published articles. Other interventions should be assessed and considered in the future. Trial Registration:  ClinicalTrials.gov Identifiers: NCT05820971 (CONSORT-PR) and NCT05820984 (SPIRIT-PR

The maximum alcohol withdrawal syndrome score associates with worse clinical outcomes - A retrospective cohort study

Background: The Wetterling alcohol withdrawal syndrome (AWS) scale determines withdrawal severity and guides treatment. We investigated associations between maximum AWS scores and clinical outcomes. Methods: This retrospective cohort study considered AWS assessments measured from 8/2015-8/2017. We used multivariable linear and logistic regression to analyze associations between the maximum score and increased length of stay (LOS) and in-hospital mortality, respectively. Firstly, we investigated the maximum score of all AWS assessments any time during the stay, secondly, the maximum measured only within the first 3 days of withdrawal. Results: A total of 2,464 hospital stays showed that, patients with “mild” (9) maximum scores had median LOS of 5.93, 9.35, 14.71 days, mortality was 1.7%, 4.8%, 8.0%, respectively. Regression showed that a higher maximum score was independently associated with increased LOS and mortality (both p < 0.001). Based on the maximum AWS score within the first 3 days, the median LOS was 6.18, 9.00, 12.89 days, mortality was 2.2%, 3.6%, 7.6%, respectively. A higher maximum score in the first 3 days was independently associated with increased LOS (p = 0.036) and mortality (p = 0.001). Severe maximum AWS scores within 3 days of withdrawal had an odds ratio of 2.53 (95% CI: 1.27, 4.82; p = 0.0060) for in-hospital death. Conclusions: Maximum AWS scores associate independently with increased LOS and in-hospital mortality. This association is reproducible within the first 3 days of withdrawal. Development of such a 3-day tool could help clinicians assess the risk of worse clinical outcomes early on and adjust care accordingly

Bridging the Gap: identifying factors impacting mRNA SARS-CoV-2 vaccine booster response in people living with HIV-1

OBJECTIVES: This study aimed to investigate the association of demographic and clinical characteristics, including HIV-specific parameters with the antibody response to a third dose of a SARS-CoV-2 mRNA vaccine in people living with HIV-1 (PWH). DESIGN: Post-hoc analysis of data collected during the observational extension of the COrona VaccinE tRiAL pLatform trial (COVERALL-2) nested into the Swiss HIV Cohort Study. METHODS: Serological measurements were conducted on a total of 439 PWH who had received a third dose of either mRNA-1273 (Moderna) or BNT162b2 (Pfizer-BioNTech) SARS-CoV-2 vaccine. Antibody reactivity was assessed using the multifactorial ABCORA immunoassay that defines SARS-CoV-2 seroconversion and predicts neutralization activity. The association between log transformed antibody reactivity and various baseline factors, including vaccine type, demographics, immune and viral status, smoking status, co-morbidities, infection history, and co-medication with chemotherapy and immunosuppressive drugs, was investigated using a multivariable linear regression model. RESULTS: Antibody response against SARS-CoV-2 after a third vaccination was significantly lower among PWH with CD4 cell count <350 cells/μl (ratio of means (RM) 0.79; 95% confidence interval (CI) 0.65-0.95). Having a detectable HIV-1 viral load ≥50 copies/ml and being on concurrent chemotherapy was associated with an overall lower humoral immune response (RM 0.75; 95% CI 0.57-1.00 and 0.34; 95% CI 0.22-0.52, respectively). CONCLUSIONS: The study highlights the importance of optimal antiretroviral treatment (ART) for PWH, emphasizing the need for timely intervention to enhance the vaccine immunogenicity in this population. Moreover, it underscores the significance of sequential mRNA vaccination and provides important evidence for informing vaccine guidelines

Nonregistration, discontinuation, and nonpublication of randomized trials: A repeated metaresearch analysis.

BackgroundWe previously found that 25% of 1,017 randomized clinical trials (RCTs) approved between 2000 and 2003 were discontinued prematurely, and 44% remained unpublished at a median of 12 years follow-up. We aimed to assess a decade later (1) whether rates of completion and publication have increased; (2) the extent to which nonpublished RCTs can be identified in trial registries; and (3) the association between reporting quality of protocols and premature discontinuation or nonpublication of RCTs.Methods and findingsWe included 326 RCT protocols approved in 2012 by research ethics committees in Switzerland, the United Kingdom, Germany, and Canada in this metaresearch study. Pilot, feasibility, and phase 1 studies were excluded. We extracted trial characteristics from each study protocol and systematically searched for corresponding trial registration (if not reported in the protocol) and full text publications until February 2022. For trial registrations, we searched the (i) World Health Organization: International Clinical Trial Registry Platform (ICTRP); (ii) US National Library of Medicine (ClinicalTrials.gov); (iii) European Union Drug Regulating Authorities Clinical Trials Database (EUCTR); (iv) ISRCTN registry; and (v) Google. For full text publications, we searched PubMed, Google Scholar, and Scopus. We recorded whether RCTs were registered, discontinued (including reason for discontinuation), and published. The reporting quality of RCT protocols was assessed with the 33-item SPIRIT checklist. We used multivariable logistic regression to examine the association between the independent variables protocol reporting quality, planned sample size, type of control (placebo versus other), reporting of any recruitment projection, single-center versus multicenter trials, and industry versus investigator sponsoring, with the 2 dependent variables: (1) publication of RCT results; and (2) trial discontinuation due to poor recruitment. Of the 326 included trials, 19 (6%) were unregistered. Ninety-eight trials (30%) were discontinued prematurely, most often due to poor recruitment (37%; 36/98). One in 5 trials (21%; 70/326) remained unpublished at 10 years follow-up, and 21% of unpublished trials (15/70) were unregistered. Twenty-three of 147 investigator-sponsored trials (16%) reported their results in a trial registry in contrast to 150 of 179 industry-sponsored trials (84%). The median proportion of reported SPIRIT items in included RCT protocols was 69% (interquartile range 61% to 77%). We found no variables associated with trial discontinuation; however, lower reporting quality of trial protocols was associated with nonpublication (odds ratio, 0.71 for each 10% increment in the proportion of SPIRIT items met; 95% confidence interval, 0.55 to 0.92; p = 0.009). Study limitations include that the moderate sample size may have limited the ability of our regression models to identify significant associations.ConclusionsWe have observed that rates of premature trial discontinuation have not changed in the past decade. Nonpublication of RCTs has declined but remains common; 21% of unpublished trials could not be identified in registries. Only 16% of investigator-sponsored trials reported results in a trial registry. Higher reporting quality of RCT protocols was associated with publication of results. Further efforts from all stakeholders are needed to improve efficiency and transparency of clinical research
