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

purposeTo determine the number of cases required to achieve a specified recurrence-free rate (>80%) among urethroplasty types. MATERIALS AND

methodsA retrospective analysis of consecutive patients, who underwent urethroplasty performed by a single surgeon between April 2013 and January 2019, was conducted. Urethroplasty subtypes were divided according to stricture location: penile, bulbar, and posterior. If there was no recurrence for >6 months after surgery, the surgery was considered to be a success. The average success rates among quintile groups were compared to determine the learning curve for each type.

resultsOf 150 patients who underwent urethroplasty, 112 were included in this study. The overall success rate was 89.7% in penile, 97.8% in bulbar, and 74.1% in posterior urethroplasty. Bulbar urethroplasty reached the target success rate in the first quintile group (1-9 cases). Penile urethroplasty also achieved the target success rate in the first quintile group (1-8 cases), and the success rate gradually increased until the fifth quintile group (32-39 cases). In posterior urethroplasty, the target success rate was achieved in the fifth quintile group (20-27 cases).

conclusionsBulbar urethroplasty had the fastest learning curve, and posterior urethroplasty the slowest.
