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 coronavirus disease 2019 (COVID-19) pandemic highlighted the critical need for broad-spectrum antivirals with high resistance barriers. Here, we demonstrate that SB431542, a selective TGF-β receptor I (ALK5) inhibitor, exhibits potent antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through unprecedented multitargeted mechanisms. Through comprehensive IMPORTANCE: The COVID-19 pandemic highlighted the urgent need for antiviral drugs with high barriers to resistance. This study reveals that SB431542, a drug previously developed to inhibit TGF-β signaling, exhibits remarkable effectiveness against SARS-CoV-2 through an unprecedented triple-mechanism approach. Unlike conventional antivirals that target a single viral component, SB431542 simultaneously disrupts viral entry, assembly, and release by binding to the viral ORF3a protein and modulating host cellular processes. Most importantly, SARS-CoV-2 failed to develop resistance against SB431542 even after 50 generations of exposure-a significant advantage over current therapeutics that quickly lose effectiveness due to viral mutations. Our findings also uncover that coronaviruses exploit both lysosomal dysfunction and programmed cell death to spread efficiently, providing new targets for therapeutic intervention. This research establishes SB431542 as a promising broad-spectrum coronavirus inhibitor and demonstrates the value of targeting host-virus interactions to overcome antiviral resistance.
