Tongxie Yaofang ameliorates IBS-D by targeting the gut microbiota-derived tryptophan metabolites and AhR signaling axis.

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.
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 and aims: Tongxie Yaofang (TXYF) is a classic prescription for IBS-D with liver depression and spleen deficiency, with its therapeutic mechanisms requiring further elucidation. This study investigated the modulatory effects of TXYF on the gut microbiota and microbiota-derived metabolism in an IBS-D rat model to elucidate the underlying mechanisms. Methods: HPLC was employed to identify the main components of TXYF. An IBS-D rat model was replicated using a triple-factor approach that combined neonatal maternal separation, chronic restraint stress, and oral gavage of Results: TXYF significantly alleviated IBS-D symptoms in rats, including diarrhea and abdominal pain, and improved both depressive-like behavior and intestinal barrier function. Treatment with TXYF increased the abundance of Conclusion: TXYF may alleviate IBS-D symptoms and restore barrier function by increasing the abundance of
