Evaluation of non-invasive tests as diagnostic tools in assessment of bladder outlet obstruction severity in men with anterior urethral stricture.
Article in Central European journal of urology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07403786 (Urethral Resistive Index), 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
introductionThe aim of this article was to evaluate non-invasive tests, which were typically used in preoperative diagnosis of male patients with anterior urethral strictures in the assessment of the urethral resistance caused by urethral occlusion. MATERIAL AND
methodsA total of 63 adult males with confirmed urethral stricture and aged below 55 years old were enrolled in the study. Data obtained from non-invasive tests such as uroflowmetry (UF), ultrasound examination (USG), and questionnaires such as from The International Prostatic Symptom Score (IPSS), and The Patient-Reported Outcome Measure for Urethral Stricture Surgery (USS-PROM) were analyzed.
resultsAmong all analyzed non-invasive tests, bladder wall thickness (BWT) showed the highest correlation with the degree of urethral occlusion described as percentage of preserved urethral lumen (r = -0.70; p <0.0001). UF variables presented medium degree of correlation, with maximum flow rate (Qmax) as the best parameter (p = 0.45; p = 0.0005). Results from both questionnaires did not show any correlation with the severity of the urethral stricture. Multiple linear regression analysis showed that only BWT was an independent predictor in detection degree of urethral occlusion.
conclusionsUF and USG seem to be useful additional diagnostic tools in assessment severity of urethral occlusion in men suffering from anterior urethral stricture. Among them, USG had the highest correlation with degree of urethral occlusion.
