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

Porcine epidemic diarrhea virus (PEDV), a member of the Coronaviridae family, infects the small intestinal epithelial cells of pigs, causing porcine epidemic diarrhea (PED), which is particularly severe in young piglets. Owing to its strong immunogenicity, the S1 subunit of the PEDV spike (S) protein mediates viral invasion by recognizing host cell receptors and inducing neutralizing antibodies. However, effective antiviral drugs against PEDV are lacking, and current control measures are limited. In this study, the truncated S1 protein was expressed and used in surface plasmon resonance screening of 416 natural compounds. Salvianolic acid A (SalA) exhibited the strongest antiviral activity against PEDV, with a dissociation constant KD of 4.54 × 10⁻⁷ M. Molecular docking revealed multiple hydrogen bonds between SalA and key amino acid residues of the S1 protein. IMPORTANCE: Porcine epidemic diarrhea virus (PEDV) causes severe diarrhea and high mortality in piglets, resulting in substantial economic losses to the global swine industry. However, effective antiviral therapeutics are still lacking. In this study, salvianolic acid A (SalA), a natural polyphenolic compound derived from
