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

Cenicriviroc (CVC) is a small-molecule chemokine receptor antagonist with highly potent and selective anti-human immunodeficiency virus type 1 (HIV-1) activity through antagonizing C-C chemokine receptor type 5 (CCR5) as a coreceptor of HIV-1. CVC also strongly antagonizes C-C chemokine receptor type 2b (CCR2b), thereby it has potent anti-inflammatory and immunomodulatory effects. CVC is currently under clinical trials in the patients for treatment of nonalcoholic steatohepatitis, in which immune cell activation and dysregulation of proinflammatory cytokines play an important role in its pathogenesis. In this study, CVC was examined for its inhibitory effect on the replication of SARS-CoV-2, the causative agent of COVID-19, in cell cultures and found to be a selective inhibitor of the virus. The 50% effective concentrations of CVC were 19.0 and 2.9 μM in the assays based on the inhibition of virus-induced cell destruction and viral RNA levels in culture supernatants of the infected cells, respectively. Interestingly, the CCR5-specific antagonist maraviroc did not show any anti-SARS-CoV-2 activity. Although the mechanism of SARS-CoV-2 inhibition by CVC remains to be elucidated, CCR2b does not seem to be its target molecule. Considering the fact that the regulation of excessive immune activation is required to treat COVID-19 patients at the late stage of the disease, CVC should be further pursued for its potential in the treatment of SARS-CoV-2 infection.
