Chronic use of renin-angiotensin-aldosterone system blockers and mortality in COVID-19: A multicenter prospective cohort and literature review.
Article in Fundamental & clinical pharmacology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04262921 (Clinical Characterisation Protocol for Severe Emerging Infections), which is not on this map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
aimsThe role of renin-angiotensin-aldosterone system (RAAS) blockers on the course of coronavirus disease 2019 (COVID-19) is debated. We assessed the association between chronic use of RAAS blockers and mortality among inpatients with COVID-19 and explored reasons for discrepancies in the literature. METHODS AND
resultsWe included adult hypertensive patients from a prospective nationwide cohort of 3512 inpatients with COVID-19 up to June 30, 2020. Cox proportional hazard models with various adjustment or propensity weighting methods were used to estimate the hazard ratios (HR) of 30-day mortality for chronic users versus non-users of RAAS blockers. We analyzed data of 1160 hypertensive patients: 719 (62%) were male and 777 (67%) were older than 65 years. The main comorbidities were diabetes (n = 416, 36%), chronic cardiac disease (n = 401, 35%), and obesity (n = 340, 29%); 705 (61%) received oxygen therapy. We recorded 135 (11.6%) deaths within 30 days of diagnosis. We found no association between chronic use of RAAS blockers and mortality (unadjusted HR = 1.13, 95% CI [0.8-1.6]; propensity inverse probability treatment weighted HR = 1.09 [0.86-1.39]; propensity standardized mortality ratio weighted HR = 1.08 [0.79-1.47]). Our comprehensive review of previous studies highlighted that significant associations were mostly found in unrestricted populations with inappropriate adjustment, or with biased in-hospital exposure measurement.
conclusionOur results do not support previous concerns regarding these drugs, nor a potential protective effect as reported in previous poorly designed studies and meta-analyses. RAAS blockers should not be discontinued during the pandemic, while in-hospital management of these drugs will be clarified by randomized trials. NCT04262921.
