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
introductionThe aim of this study was to evaluate testicular perfusion and vascularization with intraoperative ICG/NIR imaging in a testicular ischemia-reperfusion model and to investigate the effects of ICG on testicular tissue. MATERIALS AND
methods24 male rats were divided into four groups. In the ICG group, only ICG was given and images of the testicles were recorded with NIR camera. In the torsion group, the testicles were left in torsion for 4 h. ICG/NIR images were obtained after torsion and detorsion. In the reperfusion group, ICG/NIR images of the testicles were obtained at the 4
resultsThere was no histologically negative effect of ICG on testicular tissue. There was no testicular perfusion in the torsion group, but perfusion started after detorsion. At the 4th hour of reperfusion, testicular perfusion continued. TNF-a, IL-6, MCP-1 and caspase-3 immunoreactivity were found to be at low levels in the control and ICG groups, while high in the torsion and reperfusion groups (p < 0.05). In qRT-PCR, TNF-a, IL-6, MCP-1 and caspase-3 expressions were lower in the control and ICG groups, but higher in the torsion and reperfusion groups.
conclusionThere was no histologically negative effect of ICG on testicles. The ICG/NIR imaging technique seems to be a feasible method in testicular torsion and may contribute to the surgeon in the intraoperative management of testicular torsion. In testicles that started to be perfused after detorsion, perfusion still continued at the 4th hour of reperfusion. Our next goal is to test whether testicles showing ICG fluorescence in during reperfusion maintain their viability for long term.
