Effect of Varicocelectomy on Serum FSH and LH Levels for Patients with Varicocele: a Systematic Review and Meta-analysis.
Article in The Indian journal of surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Varicocelectomy can improve the function of testicular Leydig cell for patients with varicocele. We carried out a systematic review and meta-analysis to assess effect of varicocelectomy on serum FSH and LH levels for patients with varicocele. A literature review was performed to identify all published randomized preoperation-postoperation clinical trials of assessing serum FSH and LH levels before and after varicocelectomy. The search included the following databases: PUBMED and EMBASE. The reference lists of retrieved studies were also investigated. A systematic review and meta-analysis were conducted. Five studies were selected from 149 studies, including 312 patients. The meta-analysis showed that serum FSH level (95% confidence interval 0.19-0.77,
