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

purposeTo determine the efficacy of different surgical approaches and techniques for resolving varicocele-related pain and factors that predict surgical outcomes.

methodsThe PubMed and Embase databases were searched with the terms "varicocele", "varicocelectomy" and "pain". Manual searches by reviewing the references of included studies were performed. Studies were included when they focused on the influence of varicocele grade, pain quality, different surgical approaches or techniques on pain resolution. A meta-analysis was conducted with RevMan5.3 software.

resultsTwelve studies were identified in the analysis. No significant correlation was found between varicocele grade and pain resolution (P > 0.05). The resolution rate for dull pain was significantly higher than sharp pain [RR = 1.11, 95 % CI (1.02, 1.22), P = 0.02], and there were no other significant differences between the qualities of pain and pain resolution. The pain resolution rate was significantly higher after subinguinal varicocelectomy than after high or inguinal varicocelectomy [RR = 0.83, 95 % CI (0.76, 0.90), P < 0.00001 and RR = 0.92, 95 % CI (0.86, 0.99), P = 0.02]. The pain resolution rate was significantly higher after microsurgery than after laparoscopic varicocelectomy [RR = 0.77, 95 % CI (0.60, 0.99), P = 0.04].

conclusionSubinguinal varicocelectomy and microsurgical varicocelectomy are efficacious for resolving varicocele-related pain compared to other approaches and techniques. Pain quality is a factor that predicts surgical outcomes while varicocele grade is not. Additional controlled studies are warranted to clearly define this clinical problem.
