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

backgroundTesticular torsion/detorsion triggers tissue ischemia/reperfusion, leading to reactive oxygen species overgeneration and apoptosis. The saliva of leeches is full of anti-inflammatory, anticoagulants, antioxidants, and antimicrobial agents. Therefore, this study aimed to assess the protective mechanism of leech therapy on testicular ischemia/reperfusion damage.

methods18 adult male rats were randomly divided into three groups: 1-Sham-operated group (SO). 2-Torsion/detorsion (T.D) group: two hours of testicular torsion with two hours of testicular detorsion was performed. 3-Torsion/detorsion + Leech therapy (TDL) group. Sperm parameters (motility, vitality, morphology, and concentration), oxidative stress biomarkers (MDA, CAT, GPx, and TAC), histopathological factors (Mean seminiferous tubular diameter, Germinal epithelial cell thickness, Testicular capsule thickness, Johnson's score, and Cosentino's score), and immunohistochemical markers for apoptosis detection (Bax, Bcl-2, and Caspase-3) were measured.

resultsThere was a significant difference for all sperm parameters in the T. D group compared to the sham group. Leech therapy significantly increased progressive motility and normal morphology and reduced non-progressive motility. In the TDL group, MDA concentration significantly reduced, and levels of GPx, TAC, and CAT remarkably increased. All evaluated histopathological parameters in the TDL group significantly increased compared to the T. D group except for the testicular capsule thickness. T. D notably increased the expression of Bax and Caspase-3, while the treatment group slowed the rate of apoptosis compared to the control group. Bcl-2 expression in the T. D group was significantly lower than that in the sham group. Leech therapy increased the Bcl-2 expression.

conclusionLeech therapy attenuates damages to testicular tissue following torsion/detorsion due to its antioxidant, anti-inflammatory, and anti-apoptotic effects. Hence, it can be considered as an effective remedy for testicular ischemia/reperfusion.
