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
Background/aim: This study describes ventral-approach augmented nontransected anastomotic (vANTA) urethroplasty and presents the preliminary functional results of patients treated with this technique. Materials and methods: Twenty-three patients who underwent vANTA urethroplasty were included in the study. Stricture location, stricture length, preoperative uroflowmetry parameters (maximum flow rate (Qmax) and mean flow rate (Qmean)), preoperative International Index of Erectile Function (IIEF)-5 scores, operation time, postoperative complications, length of hospital stay, and follow-up periods were recorded. The Qmax, Qmean, and IIEF-5 scores of the patients were recorded again in the second and twelfth postoperative months. Preoperative and postoperative Qmax values and IIEF-5 scores were compared. Kaplan-Meier survival analysis was performed to demonstrate recurrence-free survival. Results: The mean age of the patients included in the study was 52.1 ± 16.9 years. Mean stricture length was 2.5 ± 0.5 cm. There was a statistically significant difference between preoperative and 2-month postoperative uroflowmetry Qmax values (6.9 (0.0-14.5) vs. 18.5 (5.5-41.5) mL/s; p < 0.001). There was no statistically significant difference in preoperative and 2-month postoperative IIEF-5 scores (p > 0.05). There was a statistically significant difference between preoperative and 1-year postoperative median Qmax values (7.2 (0.0-12.3) vs. 17.4 (11.2-24.3) mL/s; p = 0.001). There was no statistically significant difference between preoperative and 1-year postoperative IIEF-5 scores (p > 0.05). According to Kaplan-Meier recurrence-free survival analysis, the recurrence-free survival rate at 6 months was 95.7. Conclusion: In cases of bulbar urethral strictures, vANTA urethroplasty is an effective treatment option with limited postoperative complications. Preserving the underlying corpus spongiosum is important to avoid impaired sexual function.
