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

Background: The gut microbiota plays a vital role in various physiological processes, including metabolism. Fecal microbiota transplantation (FMT) involves transferring fecal matter from a healthy donor to rebalance a patient's intestinal dysbiosis. The impact of FMT on metabolic syndrome (MetS) is subject to debate. This study assesses the effects of FMT on MetS when administered by rectal enema. Methods: In a double-blind, randomized controlled trial, subjects with MetS were assigned to receive either FMT (n=8) or a sham intervention (n=10) via rectal enema. Participants were followed at 6 and 12 weeks. The primary outcome was changes in the homeostatic model assessment of insulin resistance (HOMA-IR). Secondary outcomes included fasting blood glucose (FBG), body mass index (BMI), inflammatory markers, and hepatic steatosis. The mean adjusted difference (MAD) and 95% confidence interval (CI) between groups were reported as treatment effects using a linear marginal model for repeated measures. Results: The study included patients with a mean age of 50.4±10.7 years. Baseline BMI and HOMA-IR were similar between groups. Over 6 weeks, FMT significantly improved HOMA-IR (MAD, -1.63; 95% CI, -2.63 to -0.64; Conclusion: FMT by rectal enema produced favorable changes in IR in patients with MetS. FMT may be an effective treatment for patients with metabolism-related diseases. Further research into the long-term benefits of the procedure is warranted.
