The comparison of the effect of phenylephrine and epinephrine on penile spongy tissue in rats after experimental hypospadias surgery: a quantitative stereological study.
Article in BMC urology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundMany factors including vasoconstrictor agents can interfere with wound healing process. This study aimed to compare the histopathological outcome of injection of two sympathomimetic drugs used during urologic surgery, including phenylephrine and epinephrine, on the structure of spongy tissue and urethra in a rat model of experimental hypospadias repair using stereological methods.
methodsMale rats were allocated into three groups. The first group underwent surgery without using any agents. The second and third groups underwent surgery with diluted phenylephrine (1:5000) and diluted epinephrine (1:100000) injection in the urethral plate before operation, respectively. Quantitative histological evaluation of all penises was performed after 3 weeks.
resultsThe results indicated no significant differences among the three groups regarding the vessels and urethral lumen and epithelium. However, the volumes of the spongy tissue and collagen bundles and the number of fibroblasts were significantly higher (35-55%) in surgery + phenylephrine and surgery + epinephrine groups in comparison to the surgery group (p < 0.05), with no preferences.
conclusionsHypospadias repair using phenylephrine and epinephrine injection showed no adverse effects. Furthermore, they might lead to better postoperative structural outcomes without any preferences. However, further experimental and human studies are required to draw a firm conclusion.
