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
introductionThis study aimed to translate, culturally adapt, and evaluate the psychometric properties of four patient-reported outcome measures developed for individuals with overactive bladder (OAB): the Overactive Bladder Questionnaire (OAB-Q), Urgency Questionnaire (UQ), Primary Overactive Bladder Symptom Questionnaire (POSQ), and Patient Perception of Bladder Condition (PPBC).
methodsThe study included 120 women diagnosed with OAB. The Turkish adaptation of the instruments was conducted using a standardized forward-backward translation and cultural adaptation process, and content validity was assessed on the basis of expert opinions. For test-retest reliability, participants completed the questionnaires twice with a 2-week interval. Internal consistency was evaluated using Cronbach's alpha coefficient, while test-retest reliability was examined using intraclass correlation coefficients (ICC) and Cohen's kappa analysis. Construct validity was assessed using exploratory and confirmatory factor analyses. Convergent and discriminant validity were analyzed using the King's Health Questionnaire (KHQ), bladder diary variables, and the pad test.
resultsCronbach's alpha coefficients ranged from 0.781 to 0.945 for the OAB-Q and from 0.795 to 0.910 for the UQ. The total Cronbach's alpha value for the POSQ was 0.70. Test-retest results demonstrated moderate to high temporal stability across all instruments. Factor analyses supported the original factor structures of the scales. A significant and moderate correlation was found between the POSQ and the KHQ, whereas the PPBC demonstrated independent construct validity by reflecting patients' subjective perceptions of their bladder condition.
conclusionThe Turkish versions of these four instruments are valid, reliable, and culturally appropriate assessment tools for evaluating OAB symptoms, with potential utility in both clinical practice and research settings.
