1 · What the graph read from 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.

2 · The registry

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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

aimsAngiotensin-converting enzyme-2 (ACE2) is the receptor for SARS-CoV-2. Animal studies suggest that renin-angiotensin-aldosterone system (RAAS) blockers might increase the expression of ACE2 and potentially increase the risk of SARS-CoV-2 infection. METHODS AND

resultsThe effect of ACE inhibitor (ACEI) treatment on the pneumonia incidence in non-COVID-19 patients (25 studies, 330 780 patients) was associated with a 26% reduction of pneumonia risk (odds ratio [OR]: 0.74, P < .001). Pneumonia-related death cases in ACEI-treated non-COVID-19 patients were reduced by 27% (OR: 0.73, P = .004). However, angiotensin II receptor blockers (ARB) treatment (10 studies, 275 621 non-COVID-19 patients) did not alter pneumonia risk in patients. Pneumonia-related death cases in ARB-treated non-COVID-19 patients was analysed only in 1 study and was significantly reduced (OR, 0.47; 95% confidence interval, 0.30 to 0.72). Results from 11 studies (8.4 million patients) showed that the risk of getting infected with the SARS-CoV-2 virus was reduced by 13% (OR: 0.87, P = .014) in patients treated with ACEI, whereas analysis from 10 studies (8.4 million patients) treated with ARBs showed no effect (OR, 0.92, P = .354). Results from 34 studies in 67 644 COVID-19 patients showed that RAAS blockade reduces all-cause mortality by 24% (OR = 0.76, P = .04).

conclusionACEIs reduce the risk of getting infected with the SARS-CoV-2 virus. Blocking the RAAS may decrease all-cause mortality in COVID-19 patients. ACEIs also reduce the risk of non-COVID pneumonia. All-cause mortality due to non-COVID pneumonia is reduced by ACEI and potentially by ARBs.
