The Association Between the Rate of Angiotensin-Converting Enzyme Inhibitors and Angiotensin Receptor Blockers Use and the Number of Covid-19 Confirmed Cases and Deaths in the United States: Geospatial Study.
Article in medRxiv : the preprint server for health sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe novel coronavirus SARS-Cov2 uses the angiotensin-converting enzyme 2 (ACE2) receptor as an entry point to the cell. Cardiovascular disease (CVD) is a risk factor for the novel coronavirus disease (Covid-19) with poor outcomes. We hypothesized that the rate of ACE inhibitor (ACEI) and angiotensin receptor blocker (ARB) use is associated with the rate of Covid-19 confirmed cases and deaths.
methodsWe conducted a geospatial study using publicly available county-level data. The Medicare ACEI and ARB prescription rate was exposure. The Covid-19 confirmed case and death rates were outcomes. Spatial autoregression models were adjusted for the percentage of Black residents, children, residents with at least some college degree, median household income, air quality index, CVD hospitalization rate in Medicare beneficiaries, and CVD death rate in a total county population.
findingsAfter adjustment for confounders, the ACEI use rate did not associate with Covid-19 confirmed case rate (direct county-own effect +0.11 %; 95%CI -0.31 to 0.53; P=0.600, and indirect spillover effect -0.53 %; 95%CI -3.89 to 2.84; P=0.760). The ARB use rate was associated with increased Covid-19 confirmed case rate (direct county-owned effect +0.12 %; 95%CI 0.05-0.19; P=0.002, and indirect spillover effect -0.33 %; 95%CI -2.11 to 1.44; P=0.714). Sensitivity analysis indicated an absence of significant reverse causality bias for analyses with Covid-19 confirmed case rate, but not death rate outcome.
interpretationOur results highlight the safety of ACEI use for patients with clinical indications for ACEI use. However, an increase in ARB use by 1% was associated with a 0.12 % increase in Covid-19 confirmed cases. The use of ARB, due to known ACE2 upregulation, may facilitate SARS-CoV-2 entry into target cells and increase infectivity. Cluster-randomized controlled trial is warranted to answer the question of whether the replacement of ARB by ACEI may reduce the Covid-19 confirmed case rate.
