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

In this study, three KRN7000 analogues with variations in the sugar and glycosidic linkage were synthesised to assess their efficacy in disrupting the biofilms of S. pyogenes and P. mirabilis. All three analogues exhibited antibacterial activity, with the effects being more prominent at lower concentrations in S. pyogenes. The N-alkylated, 1-deoxy analogue emerged as the most effective, significantly reducing biofilm formation and extracellular polymeric substances (EPS) in both organisms. Microscopic analysis revealed notable disruption of biofilm structure by the analogue, resulting in a significant reduction in EPS for both organisms and decreasing cell surface hydrophobicity. These results position the KRN7000 analogue as a promising candidate for developing glycolipid-based antibiofilm agents.
