This retrospective study determined the characteristics and prognostic factors of COVID-19 patients, focusing on inpatients who died or were discharged between 30 December 2019 and 29 February 2020 at Renmin Hospital of Wuhan University. We need methods to improve the comparability of the intervention and control groups.

Design Retrospective observational study. Of 1566 potentially suitable household surveys, 553 passed quality checks, covering 133 countries between 1984 and 2015. This retrospective observational study conducted in Necker Hospital for Sick Children, France (January 2018-June 2020) evaluated a potential temporal association between admissions for suicide behaviours in children and adolescents and the national COVID-19 lockdown (March-May 2020). Methods Retrospective observational study of all attendances at EDs in England during 2015/2016, applying three definitions of avoidable attendance.

Cohort study design is described as ‘observational’ because, unlike clinical studies, there is no intervention. The retrospective observational cohort study design could lead to certain types of bias (eg, confounding bias, selection bias).
