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
backgroundThis study aimed to compare the clinical outcomes of non-transecting urethroplasty and lingual mucosal urethroplasty in the treatment of iatrogenic bulbar urethral stricture.
resultsA total of 25 patients with iatrogenic bulbar urethral stricture were enrolled, 12 of whom underwent lingual mucosal urethroplasty, 13 patients who underwent non-transecting urethroplasty. All patients were followed-up and evaluated at 3 postoperative months. Evaluations included urethrography, maximum urine flow rate (Qmax), nocturnal erectile function testing, International Index of Erectile Function (IIEF-5) assessment, and Anxiety Related Scale (SAS) assessment. In terms of operation time, there was a significant difference between non-transecting urethroplasty and lingual mucosal urethroplasty. However, there was no significant intergroup difference in intraoperative blood loss. Both techniques were associated with significantly improved Qmax relative to preoperative rates, but there was no significant difference between the groups in this regard over 3 months of postoperative follow-up. Nocturnal penile tumescence and rigidity results showed that there was no significant change in tip hardness after surgery in the non-transecting urethroplasty group. Moreover, IIEF-5 scores indicated that there was no significant intergroup difference in terms of subjective postoperative erectile function. According to the preliminary psychological evaluations during postoperative follow-up, the anxiety scores of patients undergoing non-transecting urethroplasty significantly improved, but there was no significant change in the mean SAS score among patients who underwent lingual mucosal urethroplasty.
conclusionBoth surgical methods can achieve the clinical goal of treating iatrogenic bulbar urethral stricture. Non-transecting urethroplasty has the characteristics of short operation time, relative technical simplicity, and retention of the original erectile function of most patients, and the surgical outcomes of non-transecting urethroplasty are not inferior to those of lingual mucosal urethroplasty, and it is a promising technique for widespread use to treat bulbar urethral strictures.
