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
Introduction: The IBD-Control questionnaire and IBD-Disk are two patient-reported outcome measures designed to evaluate the impact of inflammatory bowel disease (IBD) on different health domains. Unlike IBD-Disk, there is no fully published validated Portuguese version of IBD-Control. Furthermore, the two instruments have not yet been compared. We aimed to translate and validate IBD-Control in Portugal and compare it with IBD-Disk. Methods: After translation into Portuguese, the IBD-Control was administered to IBD patients, at baseline (T0), after 1-4 weeks (T1), and >3 months (T2). Patients also completed the Portuguese versions of the PRO2, EQ-5D, SIBDQ, and IBD-Disk. We assessed the reliability, validity, responsiveness, and interpretability of IBD-Control. We compared the usability (3 questions) and the ability to identify good disease control (area under the curve [AUC]) of IBD-Control and IBD-Disk. Results: At T0, the IBD-Control was completed by 142 patients (108 Crohn's disease, 34 ulcerative colitis). At T1 and T2, 68 and 101 patients completed the questionnaire, respectively. Factor analysis confirmed the one-dimensionality of the scale with 8 items (IBD-Control-8). Internal consistency (Cronbach's alpha) was 0.80. Test-retest reproducibility for stable patients ( Conclusions: The IBD-Control is reliable and valid for measuring disease control from the perspective of patients with IBD in Portugal, presenting no significant differences regarding usability and assessment of disease control when compared to IBD-Disk.
