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

Shiga toxin-producing Escherichia coli (STEC) poses a significant health risk, with Stx1 and Stx2 as key virulence factors associated with hemolytic uremic syndrome (HUS). Current STEC treatment relies on supportive care, avoiding antimicrobial therapy. This study evaluates the antibacterial activity of three cecropin peptides and their effect on the expression of the stx2 gene in STEC. Employing microdilution assays and RT-qPCR, all three cecropins demonstrated antibacterial efficacy, displaying MIC and MBC values of 12.5 µg/mL, and decreased gene expression levels following treatment. Notably, these cecropins not only inhibited STEC growth but also significantly reduced stx2 mRNA expression. These findings underscore the therapeutic potential of cecropins as an alternative treatment for STEC infections and suggest they may mitigate associated complications.
