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
purposePouch-related fistulae are devastating complications of ileoanal pouch surgery, which is performed to improve the quality of life (QoL) for patients who have had a proctocolectomy. Their management is limited by inconsistent evidence, including using poorly and heterogeneously defined outcomes. This study aims to identify all Outcome Measurement Instruments (OMIs) used in pouch fistula research, including Patient-Reported Outcome Measures (PROMs) and Clinician-Reported Outcome Measures (ClinROMs) and evaluate their quality using COSMIN guidelines to help select the best tool for a standardised core outcome measurement set in a future consensus study.
methodsA systematic review was conducted to identify all OMIs used in ileo-anal pouch fistulae studies, from MEDLINE, Embase, and the Cochrane Library. We evaluated existing OMIs based on COSMIN guidelines and used the GRADE approach to assess evidence quality. Results were synthesized narratively.
resultsAmong 91 studies, 13 OMIs were reviewed. Pouch-specific instruments performed poorly in key domains of reliability, validity, and responsiveness. Only 17.6% of studies assessed QoL using PROMs. The best-performing instruments were the SF-36 and IBDQ. The Ileoanal Pouch Syndrome Severity Score was the only pouch-specific instrument that involved patients in its development and although useful for pouch dysfunction, it lacks specific QoL assessment and was not validated in pouch-fistulae patients.
conclusionExisting OMIs for pouch-related fistulae lack adequate measurement properties, with no PROMs specifically validated for QoL in this population and very few instruments involving patients in their development. There is an unmet need for a validated PROM specifically for QoL in pouch-related fistulae.
