Effectiveness of Clomiphene Citrate for Improving Sperm Concentration: A Literature Review and Meta-Analysis.
Review in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Demographic data regarding male infertility suggest an increase in prevalence. This is an entity with multifactorial etiology, hormonal causes are often encountered. Although treatment with clomiphene was advocated to stimulate gametogenesis, it is still used off-label. We aimed to evaluate data from literature related to the effect of clomiphene as a single therapy, on the improvement of sperm count in infertile patients. Out of the 4,017 results of the search, only eight articles have been selected. The selected studies have been published between 1983 and 2020, and have included a total of 616 patients. From data reported, the treatment with clomiphene lead to a significant improvement of sperm concentration compared with placebo or with the level before starting the therapy (p<0.00001). Out of the 616 patients, in 369 (59.90%) cases improved sperm concentration was reported. In our meta-analysis, the selected studies had a high heterogeneity (I
