Structural basis of SARS-CoV-2 polymerase inhibition by nonnucleoside inhibitor HeE1-2Tyr.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Targeting the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2 with small molecules is a promising therapeutic strategy against COVID-19, but potent and safe inhibitors are lacking. HeE1-2Tyr, a nonnucleoside inhibitor of Dengue virus RdRp, was also shown to inhibit SARS-CoV-2 RdRp in vitro and to have antiviral activity in cells, but the underlying mechanism remains unclear. Here, we elucidate the molecular mechanism of HeE1-2Tyr-mediated SARS-CoV-2 RdRp inhibition. Biochemical assays confirm that HeE1-2Tyr inhibits RdRp with an IC
