1 · What the graph read from it

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.

2 · The registry

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

backgroundThe presentation and management of the recurrent urethral stricture varies and depends largely on the initial treatment and the characteristics of the recurrent stricture. What are the likely determinants of recurrence? PATIENTS AND

methodsThis is a retrospective review of all patients who had urethroplasties from January 2013 to December 2017 for anterior urethral strictures in our institution. Patients with a recurrence of the strictures were identified and reviewed, while patients with hypospadias and posterior urethral stenosis or contractures were excluded from the study. The etiology, length, site, and type of urethroplasties were evaluated as variables that may contribute to the recurrence of strictures using inferential statistics and logistic regression analysis. Time to recurrence was analyzed using the Kaplan-Meier method.

resultsA total of 206 urethroplasties for anterior urethral strictures were evaluated with recurrence of strictures noted in 29 patients and a recurrence rate of 14.1%. Recurrence was higher in long-segment strictures, penobulbar strictures, and postinflammatory strictures. Pedicle flaps were used in 45% of the strictures that reoccurred. Using Chi-square, the length, site, of urethroplasties were statistically significant determinants of recurrence; however, only the site of stricture was found to be statistically significant following logistic regression analysis. The site of recurrence was in the bulbar urethra in 79% and the penile urethra in 21%. The choice of treatment of the recurrent strictures was anastomotic urethroplasty in 76.5%. The mean time to failure in this study was 13 months with a range of 6-120 months.

conclusionIn this study, the site of stricture was found to be the most determinant of stricture recurrence, with penobulbar strictures mostly implicated. Long-segment strictures were also noted to contribute to some extent in recurrence. These recurrent strictures were mostly short-segment strictures in the bulbar urethra which were amenable to excision and anastomosis to achieve cure.
