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 may influence Parkinson's disease's (PD) pathophysiology. Faecal Microbiota Transplantation (FMT) may therefore improve symptoms. We reviewed five randomized controlled trials (RCT), three cohort studies, one case series, and two single case reports (total of 236 subjects). FMT methods varied (donor selection, FMT preparation method, pre-treatment, administration). Mild, self-limiting gastrointestinal symptoms were the most common adverse events (AEs). Constipation improved consistently after FMT. Motor and non-motor outcomes were heterogeneous, with improvements mainly reported in uncontrolled studies. One RCT demonstrated motor improvement at 8-12 weeks, another only after one year, while others showed no significant changes. In most RCTs, changes fell within or just beyond the minimal clinically important differences (MCID). Five studies reported taxonomic shifts, most consistently increased within the phylum Firmicutes. Large, well-designed RCTs with optimized FMT protocol for patient selection, FMT preparation and delivery, and donor selection are needed to determine whether FMT can affect PD symptoms or disease progression.
