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
Objective: This study aims to explore the clinical efficacy and safety of a urethroplasty technique for fossa navicularis (FN) strictures using a transurethral annular inlay oral mucosa graft. Methods: A retrospective analysis was conducted on clinical data from patients with urethral meatus and navicular fossa stricture who underwent transurethral reconstruction using annular inlay oral mucosa graft urethroplasty in Tangdu Hospital from July 2021 to October 2024. Operation success was defined as the ability to pass the F24 urethral probe, and the secondary outcome is the urinary flow rate and patient satisfaction at 1, 3, 6, and 12 months. Results: All 12 patients successfully completed the surgery. The average age was 56.8 ± 6.8 years, and the average length of urethral stricture was 1.6 ± 0.2 cm. Three patients had a history of transurethral endoscopic surgery, eight had penile lichen sclerosus (LS), and one had no obvious causes. Over a median follow-up of 19 months, the average maximum urinary flow rate was 21.2 ± 3.2 ml/s at 3 months, and the average maximum urinary flow rate was 19.5 ± 4.2 ml/s at 12 months. One patient experienced urine pain with a thin stream and spraying urination after 3 months. Physical examination of the urethral meatus opening scar was found, and the symptoms disappeared after urethral incision. The follow-up survey of sexual life after 1 year showed that seven patients (58.3%) had successful life within 1 year compared with two patients (16.7%) before surgery. There were no cases of erectile dysfunction and poor wound healing. The patients were either very satisfied (75%) or satisfied (25%) with the operation. All patients would recommend urethroplasty to others. Conclusion: Transurethral annular inlay oral mucosa urethroplasty for urethral meatus and navicular fossa stricture reconstruction is a safe, feasible, and effective surgical method, cosmetic effect on the penile head. This technique has advantages in improving sexual function and better penile head cosmesis.
