Pattern of varicocele vein blood gases in patients undergoing microsurgical Varicocelectomy.
Article in BMC urology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundVaricocele is known to be associated with infertility and sperm disorders. The exact cause of this ailment is not fully understood. There are limited numbers of studies where venous blood gases (VBGs) of varicocele veins were determined with conflicting results. Therefore, we have investigated the pattern of VBGs in both internal spermatic and external spermatic varicocele veins and correlation with semen quality parameters in infertile individuals who underwent left microsurgical varicocelectomy.
methodsPatients (n = 27) undergoing left microsurgical varicocelectomy at a tertiary care hospital, were included in the study. Before surgery, semen parameters and scrotal color Doppler ultrasonography was performed. During surgery, blood sample was drawn from varicocele veins (internal spermatic and external spermatic veins) and a peripheral arm vein of the same patient as a control. The VBGs of all veins under study were estimated and compared with each other. The VBGs were also correlated with various semen quality parameters. Data, expressed as Mean ± SD, regarding VBGs in three veins were analyzed using one-way ANOVA. The correlation between VBGs and semen quality parameters was determined using Pearson's correlation. Differences were considered significant at p < 0.05.
resultsThe pH was found to be higher (p < 0.01) in the internal spermatic vein compared with the external spermatic and the peripheral veins. Partial pressure of oxygen (pO
conclusionThe internal spermatic veins had higher pH and oxygen tension, but lower HCO
