A comprehensive scoring system for defecation disorders derived by merging various validated patient-reported outcome measures for fecal incontinence, chronic constipation, and obstructed defecation.

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
purposeCurrently, too many Patient-Reported Outcome Measures (PROMs) with redundant and repetitive domains are adopted to assess defecation disorders, resulting in more extended clinical visits and increased patient burden. The aim of this study was to develop a new comprehensive Defecation Disorders Scoring System (DDSS) by incorporating all items of the most commonly used and validated PROMs.
methodsThis is a prospective observational study on patients waiting for rectal prolapse and defecation disorders surgery. Preoperatively, each patient completed seven different authoritative PROMs, two questionnaires assessing constipation, two questionnaires for obstructed defecation, two questionnaires to evaluate fecal incontinence, and one questionnaire aiming to assess both. Spearman's correlation and Principal Component Analysis with varimax rotation were applied. Internal consistency was evaluated using Cronbach's α.
resultsA total of 127 female patients completed all 57 items across the seven validated PROMs and were included. Several items highly correlated with others expressing the same concept were reconsidered and excluded. A final set of 19 items was identified and arranged into DDSS, encompassing five core components regarding specific aspects of incontinence, bowel movements/defecation frequency, evacuation effort and duration, type of assistance, and abdominal discomfort. Regarding internal consistency, the derived DDSS and its five components demonstrated satisfactory results.
conclusionsThis study highlights the potential for reducing item redundancy across existing PROMs for defecation disorders. Despite some limitations, the proposed DDSS could potentially provide a concise, comprehensive tool for assessing multiple aspects of defecation disorders, potentially available in electronic format. Future studies will be required to further evaluate and validate DDSS across different patient populations.
