What Is the Best Way to Prepare A Buccal Mucosa Graft for Urethroplasty? A Histology-Based Preliminary Report.
Article in Urologia internationalis, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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 evaluate the histological characteristics of buccal mucosa samples prepared using different dissection techniques.
methodsThe buccal mucosae harvested from 9 men submitted to a substitution urethroplasty were used in this study. Biopsy specimens of buccal mucosae were grouped according to the macroscopic appearance after dissection: Group 1 - yellowish appearance (minimal dissection), Group 2 - whitish appearance (more aggressive dissection), and Group 3 - translucent appearance (ultra-aggressive dissection). The biopsy specimens were evaluated using histomorphometric techniques. The thicknesses of the graft, epithelium, and sub-epithelial connective tissue were compared.
resultsThe samples from Group 3 and Groups 2 and 3 presented lower total and lower sub-epithelial connective tissue thickness, respectively, when compared with Group 1. The epithelial thickness was not affected by the dissection method. Muscular and adipose tissues were present in 77 and 55% of samples from Group 1, respectively, whereas these were observed in 44 and 22% of samples from Group 2 respectively. The muscular tissue was observed in 11% of the cases, and the adipose tissue was not observed in samples prepared with ultra-aggressive dissection.
conclusionWe conclude that an intermediate graft dissection (whitish appearance, as performed in Group 2) presents the best balance between subepithelial connective tissue preservation and adipose and muscle tissue removal.
