EGCG as an anti-SARS-CoV-2 agent: Preventive versus therapeutic potential against original and mutant virus.
Article in Biochimie, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
In the search for anti-SARS-CoV-2 drugs, much attention is given to safe and widely available native compounds. The green tea component epigallocatechin 3 gallate (EGCG) is particularly promising because it reportedly inhibits viral replication and viral entry in vitro. However, conclusive evidence for its predominant activity is needed. We tested EGCG effects on the native virus isolated from COVID-19 patients in two independent series of experiments using VERO cells and two different treatment schemes in each series. The results confirmed modest cytotoxicity of EGCG and its substantial antiviral activity. The preincubation scheme aimed at infection prevention has proven particularly beneficial. We complemented that finding with a detailed investigation of EGCG interactions with viral S-protein subunits, including S2, RBD, and the RBD mutant harboring the N501Y mutation. Molecular modeling experiments revealed N501Y-specific stacking interactions in the RBD-ACE2 complex and provided insight into EGCG interference with the complex formation. Together, these findings provide a molecular basis for the observed EGCG effects and reinforce its prospects in COVID-19 prevention therapy.
