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

The gut microbiota is increasingly recognized as a key contributor to intestinal and brain pathologies, including Parkinson's disease (PD). Sulfate-reducing Desulfovibrio (DSV) species have emerged as microbial drivers through hydrogen sulfide and other neurotoxic factors. Using the Caenorhabditis elegans PD model NL5901 expressing human α-synuclein, we examined the effects of six DSV strains from human, animal, and environmental sources on food preference, α-syn aggregation, ROS production, gene expression, and lifespan. C. elegans strongly preferred environmental strains, particularly D. vulgaris DSM 644 (94.7% vs. 5.3% over D. piger DSM 749). In contrast, the animal isolate D. desulfuricans DSM 6949 and PD isolate D. spp. MUU 26 induced the highest α-syn aggregation (49.05 and 40.15 aggregates), ROS (3.42-fold, 3.01-fold), and sod-3, daf-16, and hsp-16.1 repression. DSM 644-fed worms exhibited a protective transcriptional profile and the greatest lifespan extension (median 36 days). These results highlight strain-specific effects of DSV on neurodegeneration, oxidative stress, and aging, reinforcing the need for mechanistic validation in mammalian PD models.
