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

Holliday junctions (HJs) are key intermediates in homologous recombination and must be processed with high precision to maintain genome stability. The bacterial resolvase RuvC has served as a model system to study this process. Here, we applied high-speed atomic force microscopy (HS-AFM) to directly visualize RuvC-DNA interactions at the single-molecule level and without the need for labeling, under near-physiological ionic conditions. HS-AFM revealed that RuvC exists as monomeric and dimeric species, and that binding to cruciform DNA mimicking HJs was associated with the dimeric form. Importantly, magnesium ions markedly enhanced the persistence of RuvC-HJ complexes, highlighting a structural role beyond catalysis. Structural predictions further supported that Mg
