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 and hypothesisThe 8-item Overactive Bladder Questionnaire (OAB-V8) is a readily available instrument for assessing overactive bladder (OAB) symptoms in clinical and research settings. Despite its established validity in Turkish, its psychometric property remains unevaluated. This study aimed to determine the responsiveness, minimal detectable change (MDC), and minimal clinically important difference (MCID) of the Turkish version of the OAB-V8.
methodsThis retrospective study consisted of 160 women (age 47.49 ± 12.07 years) with OAB who completed a standardized, guideline-adherent 8-week pelvic floor muscle training. The OAB-V8 was administered pre- and post-training. The responsiveness of the OAB-V8 was assessed using the Wilcoxon signed-rank test, standardized response means (SRMs), and effect sizes (ESs). The MDC was calculated at the 95% confidence level. Receiver operating characteristic (ROC) analysis was used to determine the MCID, maximizing both sensitivity and specificity.
resultsThe responsiveness of the Turkish version of the OAB-V8 was excellent (ES = 1.57, SRM = 1.56, p < 0.001). The MDC and MCID values were 12.97 and 12.50, respectively. The ROC analysis demonstrated excellent discriminative ability, with an area under the curve of 0.99 (sensitivity 98.0%, specificity 90.0%).
conclusionsThe main findings of this study confirm that the OAB-V8 demonstrated excellent responsiveness and discriminative ability, making it an effective tool for assessing symptoms in women with OAB. Clinicians can confidently use the Turkish version of the OAB-V8 scale to not only monitor treatment efficacy but also to determine whether the observed changes are both statistically significant and clinically relevant for the patient.
