The Effect of Biofeedback on Constipation, Sleep, Depression, Anxiety and Quality of Life in Patients with Dyssynergic Defecation: a QUASI Experimental Study (Before and After Study).

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
Dyssynergic defecation(DD) is the inability to coordinate abdominal and anorectal muscle contraction during defecation. Patients with constipation often report poor quality of life, sleep issues, and increased risk of mood disorders. Biofeedback is a recommended treatment for DD. we evaluated the effect of EMG-biofeedback on constipation symptoms as the primary outcome and also on insomnia, mood disorders (depression and anxiety), and quality of life as secondary outcomes in patients with dyssynergic defecation. Thirty-one patients with DD (74.2% women, mean age 46.23 ± 13.42 years), diagnosed using Rome IV criteria, Bristol Stool Form Scale, and anorectal manometry, were included. Patients underwent six to ten sessions of EMG-based biofeedback. We evaluated symptoms using the Wexner constipation questionnaire, Visual Analog Scale (VAS), SF-36 for quality of life, Insomnia Severity Index (ISI), and Hamilton questionnaires for anxiety and depression (HAM-A and HAM-D) before and after treatment. As consistent with study hypotheses, the Wexner scores significantly improved after biofeedback (p < 0.0001, t = 6.98). ISI scores improved (p = 0.01, t = 2.74), as did VAS scores (p < 0.0001, t = 5.14). HAM-A and HAM-D scores showed significant reductions (HAM-A: p = 0.0001, t = 5.01; HAM-D: p = 0.003, t = 2.17). However, SF-36 did not show significant improvement in quality of life (p > 0.05, t = -0.93). Biofeedback effectively improved constipation symptoms, insomnia, and mood disorders but did not impact quality of life.
