    Critical reading from the point of view of evidence-based medicine is a structured reading that allows us to evaluate the validity and relevance of the results and the applicability of a clinical study in our patient. However, the level of critical reading in resident physicians is low, as various studies have described. In a study of oncology resident physicians, a poor level of critical reading of clinical research articles was found. And in the same way, deficient levels were found in cardiology and family medicine residents. In our country, this situation is unknown and it is most likely deficient. Reason why we prepared a small review to be able to share practical bases that help the resident of specialties apply in a simpler way the critical reading of clinical studies.La lectura cr铆tica desde el punto de vista de la medicina basada en la evidencia es una lectura estructurada que nos permite evaluar la validez y pertinencia de los resultados y la aplicabilidad de un estudio cl铆nico en nuestro paciente. Sin embargo, el nivel de lectura cr铆tica en los m茅dicos residentes es baja, como se ha descrito diversos estudios. En un estudio realizado en m茅dicos residentes de oncolog铆a, se encontr贸 un nivel deficiente de lectura cr铆tica de art铆culos de investigaci贸n cl铆nica. Y de la misma forma, se encontr贸 niveles deficientes en residentes de cardiolog铆a y medicina familiar. En nuestro pa铆s, se desconoce esta situaci贸n y lo m谩s probable es que sea deficiente. Motivo por el que elaboramos una peque帽a revisi贸n para poder compartir bases pr谩cticas que ayuden al residente de especialidades cl铆nicas aplicar de una manera m谩s sencilla la lectura cr铆tica de estudios cl铆nicos

    Introduction: Despite the fact that hematological alterations at the peripheral level are widely known, little is known about the alterations caused by COVID-19 at the bone marrow level. Objective: To determine the morphological alterations of the bone marrow caused by COVID-19. Material and methods: Systematic review and meta-analysis. Observational studies and reports and case series were included and editorials, reviews, letters to the editor were excluded. A search was performed in Pubmed, ScienceDirect and Scielo. The risk of bias was assessed using the NewCatell-Ottawa and Hassan Murad scales for case reports and series. The outcomes were the morphological parameters of the bone marrow. For the quantitative synthesis of the information, a proportion meta-analysis was performed using random effects in RStudio. Results: Hypercellularity occurred in 65% (95% CI: 51%-78%), maturation arrest of the myeloid series occurred in 57% (95% CI: 29%-83%). and the alteration of the M/E ratio occurred in 60% (95% CI: 46%-74%). Conclusion: The most frequent morphological alterations in the bone marrow were hypercellularity, arrest in myeloid maturation and alteration of the M/E ratio in patients with COVID-19.Introducci贸n: Pese a conocerse ampliamente las alteraciones hematol贸gicas a nivel perif茅rico, a煤n es poco lo que se conoce acerca de las alteraciones originadas por la COVID-19 a nivel de la m茅dula 贸sea. Objetivo: Determinar las alteraciones morfol贸gicas de la m茅dula 贸sea causadas por la COVID-19. Material y M茅todos: Revisi贸n sistem谩tica y meta-an谩lisis. Se incluyeron estudios observacionales y reportes y series de caso y se excluyeron a editoriales, revisiones y cartas al editor. Se realiz贸 una b煤squeda estructurada en Pubmed, ScienceDirect y Scielo. El riesgo de sesgo se evalu贸 mediante la escala NewCatell-Otawa y de Hassan Murad para los reportes y series de caso. Los desenlaces fueron los par谩metros morfol贸gicos de la m茅dula 贸sea. Para la s铆ntesis cuantitativa de la informaci贸n se realiz贸 un meta-an谩lisis de proporci贸n mediante efectos aleatorios en RStudio. Resultados: La hipercelularidad se present贸 en el 65% (IC-95%: 51%-78%), la detenci贸n de la maduraci贸n de la serie mieloide se present贸 en el 57% (IC-95%: 29%-83%) y la alteraci贸n de la relaci贸n M/E se present贸 en el 60% (IC-95%: 46%-74%). Conclusi贸n: Las alteraciones morfol贸gicas en la m茅dula 贸sea m谩s frecuentes fueron la hipercelularidad, detenci贸n en la maduraci贸n mieloide y alteraci贸n de la relaci贸n M/E en los pacientes con COVID-19
