Statistical analysis plan for the LAKANA trial: a cluster-randomized, placebo-controlled, double-blinded, parallel group, three-arm clinical trial testing the effects of mass drug administration of azithromycin on mortality and other outcomes among 1–11-month-old infants in Mali

BACKGROUND:The Large-scale Assessment of the Key health-promoting Activities of two New mass drug administration regimens with Azithromycin (LAKANA) trial in Mali aims to evaluate the efficacy and safety of azithromycin (AZI) mass drug administration (MDA) to 1–11-month-old infants as well as the impact of the intervention on antimicrobial resistance (AMR) and mechanisms of action of azithromycin. To improve the transparency and quality of this clinical trial, we prepared this statistical analysis plan (SAP). METHODS/DESIGN: LAKANA is a cluster randomized trial that aims to address the mortality and health impacts of biannual and quarterly AZI MDA. AZI is given to 1–11-month-old infants in a high-mortality setting where a seasonal malaria chemoprevention (SMC) program is in place. The participating villages are randomly assigned to placebo (control), two-dose AZI (biannual azithromycin-MDA), and four-dose AZI (quarterly azithromycin-MDA) in a 3:4:2 ratio. The primary outcome of the study is mortality among the intention-to-treat population of 1–11-month-old infants. We will evaluate relative risk reduction between the study arms using a mixed-effects Poisson model with random intercepts for villages, using log link function with person-years as an offset variable. We will model outcomes related to secondary objectives of the study using generalized linear models with considerations on clustering. CONCLUSION: The SAP written prior to data collection completion will help avoid reporting bias and data-driven analysis for the primary and secondary aims of the trial. If there are deviations from the analysis methods described here, they will be described and justified in the publications of the trial results. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT04424511.

Working towards diagnosing bilingual children's language abilities : issues for teachers in Wales

One area of concern within a bilingual context relates to the appropriate‘diagnostic’ assessment of bilingual children’s language abilities and to thesuitable application of their assessment results in practice. Communicationand language difficulties are numerous and complex, and manifest themselvesin a variety of ways that are captured to different degrees via standardisedtests. Such tools are readily available – often in multiple forms – in somelanguages, such as English, but less readily available in others. This is particu-larly the case for minority languages such as Welsh, and this poses greatdifficulty when aiming for a certain type of assessment of specific languageabilities. This paper outlines the current state of diagnostic assessment toolsfor Welsh, with a specific focus on measures of literacy abilities. Drawing onresearch evidence from the Welsh context, we argue for appropriate trainingof educators in this area, and for the urgent need to develop tools that are bothlanguage and context specific, with relevant bilingual speaker norms, thathave practical applications in the classroom, to ensure equitable and relevantdiagnosis and support for all children educated in Wales
