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 prevalence of concomitant squamous metaplasia (SM), the initial histological change from normal urethra to urethral stricture, in bulbar urethral strictures and to investigate the associated clinical factors.

methodsA retrospective review was conducted on 165 male patients with bulbar urethral strictures who underwent excision and primary anastomosis (EPA) between 2010 and 2020, for whom complete clinical data and excised urethral specimens were available. An experienced pathologist histologically evaluated concomitant SM in paraffin sections of the proximal end of the excised urethra blinded to the clinical data. Disease duration was calculated as the period from the initial diagnosis of urethral stricture to the date of EPA. The association between concomitant SM and clinical background was investigated.

resultsSM was identified in 86 (52.1%) patients. The median disease duration in patients with SM (38 months) was significantly longer than that in patients without SM (9 months, p < 0.0001). In multivariate analysis, the longer disease duration, non-traumatic stricture etiology, and failure to maintain urethral rest with urinary diversion via a suprapubic tube for more than 90 days were independent factors predicting concomitant SM. No significant difference was observed in success rates of EPA between patients with SM (93.2%) and those without SM (97.5%, p = 0.18).

conclusionsReconstructive urologists need to be aware that concomitant SM is frequent in patients with bulbar urethral stricture, especially in those with long disease duration and those who were voiding volitionally during the period of urethral rest.
