Data sources and search strategy
A systematic literature search was conducted to identify studies
investigating the association between ACE inhibitors or ARBs and
pneumonia or COVID-19 in PubMed. The last search was updated on June
6th, 2020. The following MeSH terms were used in
PubMed: “Angiotensin-Converting Enzyme Inhibitors” or “Angiotensin
Receptor Antagonists” or “Mineralocorticoid Receptor Antagonists” and
“Pneumonia”. Detailed search terms and search strategy are described
in the supplementary file. The references cited in the retrieved studies
were hand-searched for the collection of missing relevant studies.
Details of study selection and quality assessment as well as data
extraction and analysis are provided in the supplementary materials.
