Histopathologic and clinical comparison of recurrent and non-recurrent urethral stricture disease treated by reconstructive surgery.

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
backgroundUrethral stricture is a relatively frequent problem often requiring multiple surgical interventions. The objective of this study was to compare the clinicopathologic features of urethral resections from patients who underwent open end-to-end anastomotic urethroplasty and later recurred compared to those who did not.
methodsA retrospective review of the pathology files identified 36 consecutive patients who underwent urethroplasty. The histopathological analysis included evaluation of the inflammatory infiltrate based on the predominant (>50%) cell type: lymphocyte-rich, neutrophil-rich, plasma cell-rich, and mixed; length and thickness of the fibrous plaque; and the cellularity of the fibrous plaque: cellular (>40 stroma nuclei/HPF) or paucicellular (<40 stroma nuclei/high power field).
resultsTen (28%) patients recurred, and 26 (72%) did not. There was no significant difference between recurrent and non-recurrent cases in age, race, comorbidities, location of the stricture, and etiology. All patients with recurrent strictures showed dense paucicellular fibrotic plaques (10/10; 100%), while this was seen in 14/26 (53.8%) non-recurrent cases (P=0.01). Only one patient with cellular fibrosis showed recurrence during follow-up. The log-rank test shows that time to recurrence is significantly shorter in patients with paucicellular fibrosis compared to those with cellular fibrosis (P=0.036). The inflammation consisted of a mixed population of CD3(+) T-lymphocytes, CD20(+) B-lymphocytes, and CD68(+) histiocytes, and there was no difference in the composition of the inflammation between groups. All cases with plasma cell-rich infiltrate showed normal IgG4:IgG.
conclusionsOur study supports reporting cellularity of the fibrous plaque as a potential predictor of outcome in patients undergoing reconstructive urethroplasty. Patients with paucicellular fibrosis are at increased risk of recurrence.
