Reliability and validity of the Turkish version of the core lower urinary tract symptom score in multiple sclerosis.
Observational study in Acta neurologica Belgica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06599866 (Turkish Validity and Reliability of the Core Lower Urinary Tract Symptoms Questionnaire in Patients With Multiple Sclerosis), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundIn multiple sclerosis, lower urinary tract symptoms are frequently observed depending on the site of involvement. A comprehensive assessment of these symptoms is crucial for their effective management.
objectiveThis research was designed to evaluate the validity and reliability of the Turkish adaptation of the Core Lower Urinary Tract Symptom Scale (CLSS) in patients with multiple sclerosis (PwMS).
methods71 PwMS who had an Expanded Disability Status Scale score of 6.5 or below was included. Data collection involved demographic information as well as responses to the CLSS, Overactive Bladder Questionnaire, Interstitial Cystitis Symptom Index, Interstitial Cystitis Problem Index, and International Prostate Symptom Score. To evaluate test-retest reliability, the CLSS was administered again under identical conditions after a 7-day interval.
resultsThe internal consistency of the questionnaire was assessed, resulting in a Cronbach's alpha coefficient of 0.79. Test-retest reliability for the CLSS sub-items ranged from 0.593 to 0.950. No statistically significant differences were found between the sub-items scores of the test and retest administrations. (p > 0.05). Moreover, the subscales showed significant correlations with the other questionnaires, with correlation coefficients varying between 0.109 and 0.770. Straining, feeling incomplete emptying, and pain in the bladder sub-items did not show a significant correlation with the corresponding sub-items of other questionnaires (r = 0.109, 0.270, and 0.195, respectively).
conclusionThe Turkish adaptation of the CLSS questionnaire has been proven to be a reliable and valid instrument for evaluating lower urinary tract symptoms in PwMS. CLINICALTRIALS: Gov Number: NCT06599866.
