Evaluation of the effects of antioxidant treatment on sperm parameters and pregnancy rates in infertile patients after varicocelectomy: a randomized controlled trial.

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
In this study, we aimed to evaluate the effect of oral antioxidant treatment on semen parameters and pregnancy rates in infertile men who underwent varicocelectomy. The study was conducted between January 2016 and January 2018. Subinguinal microscopic varicocelectomy was performed in 90 patients who were referred for infertility and diagnosed with clinical varicocele. The patients were divided into two groups. The first group received antioxidant treatment for 6 months after the operation (n = 62); the second group did not receive treatment after the operation (n = 28). The semen analysis was performed at the time of diagnosis and at 6 months postoperatively. The postoperative treatment semen parameters and pregnancy rates between the two groups were compared. The improvement in total sperm count ( + 45.9% vs + 26.8%), total motile sperm count ( + 50.6% vs + 29.7%), sperm concentration ( + 71.4% vs + 54.5%), sperm count in normal morphology ( + 75.7% vs + 39.9%), and total ( + 28.6% vs + 18.3%) and progressive motile sperm count ( + 60.4% vs + 38.9%) were significantly higher in the treated group than in the untreated group (p = 0.011, p < 0.001, p = 0.008, p < 0.001, p = 0.024 and p < 0.001, respectively). The clinical pregnancy rate in the first group was significantly higher than that in the second group (29% vs 17.9%) (p = 0.029). We concluded that the antioxidant treatment provides an important contribution to varicocelectomy outcomes and improves pregnancy rates.
