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

backgroundNippostrongylus brasiliensis (rat hookworm) is a key model for studying human hookworm infection.

resultsA wild N. brasiliensis isolate from Guangzhou maintains high fecundity for 10 days and persists for 21 days in rats, which is twice as long as reported for reference strains, but survives only 10 to 11 days in mice while causing more severe pathology than that observed in rats. Comparative genomic, transcriptomic, and functional analyses were conducted to explore potential genetic factors associated with these phenotypic differences. Whole-genome sequencing revealed 92.6-93.3% identity to publicly available reference assemblies. Comparative analysis of strain-specific orthogroups identified astacin metalloproteases and four collagens, three being col-117-like genes, that were exclusively expressed in parasitic L4/L5 larvae. Two of these, col-117l12 and col-117l16, were up-regulated in mouse-derived worms compared to rat-derived worms. Lentivirus-mediated RNAi of col-117l16 reduced worm burdens by 77.2%, impaired reproduction, attenuated lesions, and disrupted adult cuticle structure and intestinal positioning.

conclusionsThese findings highlight candidate genes potentially associated with N. brasiliensis life-cycle plasticity and host specificity; however, direct causal attribution of these phenotypic traits to specific genetic factors requires further validation under controlled experimental conditions.
