简要总结

The Controlled evaLuation of Angiotensin Receptor Blockers for COVID-19 respIraTorY disease (CLARITY) study is a pragmatic prospective, open-label, randomised controlled trial. CLARITY aims to examine the effectiveness of angiotensin II receptor blockers (ARBs) on improving the outcomes of people who tested positive for COVID-19 disease.
