Pharmacokinetic and Pharmacodynamic Analysis of the 3CL Protease Inhibitor Ensitrelvir in a SARS-CoV-2 Infection Mouse Model.

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
The small-molecule antiviral drug ensitrelvir targets the 3C-like protease of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study evaluated its inhibitory effect on viral replication in a delayed-treatment mouse model and investigated the relationship between pharmacokinetic (PK) parameters and pharmacodynamic (PD) effects. SARS-CoV-2 gamma-strain-infected BALB/c mice were orally treated with various doses of ensitrelvir starting 24 h post-infection. Effectiveness was determined 48 h after first administration based on lung viral titers. Ensitrelvir PK parameters were estimated from previously reported plasma concentration data and PK/PD analyses were performed. Ensitrelvir doses ≥ 16 mg/kg once daily, ≥8 mg/kg twice daily, or ≥8 mg/kg thrice daily for two days significantly reduced lung viral titers compared to that of the vehicle. PK/PD analyses revealed that mean AUC
