CJC Open 2021 Apr 6. Epub 2021 Apr 6.

Centre for Heart Lung Innovation, St. Paul's Hospital, University of British Columbia, Vancouver, BC, Canada.

Background: Angiotensin receptor blockers (ARBs) and/or angiotensin converting enzyme (ACE) inhibitors could alter mortality of COVID-19, but existing meta-analyses which combined crude and adjusted results may be confounded by comorbidities being more common in ARBs/ACE inhibitors users.

Methods: We searched PubMed/MEDLINE/Embase for cohort studies and meta-analysis reporting mortality by pre-existing ARB/ACE inhibitor treatment in hospitalized COVID-19 patients. Random effects meta-regression was used to compute pooled odds ratios for mortality adjusted for imbalance in age, sex and prevalence of cardiovascular disease, hypertension, diabetes mellitus and chronic kidney disease between users and non-users of ARBs/ACE inhibitors at the study-level during data synthesis.
