Evaluation of monotherapy of Coenzyme Q10, L-carnitine or combined therapy on semen parameters in idiopathic male infertility: A placebo-controlled double blind randomized clinical 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
Introduction: Antioxidant therapy has been proposed to improve the semen parameters in idiopathic male infertility with no clear consensus on the proper way of management. Our study aimed to evaluate the monotherapy of Coenzyme Q10 (CoQ10), L-Carnitine, or combined therapy on semen parameters in idiopathic male infertility presented with oligoasthenoteratozoospermia (OAT). Materials and methods: Two hundred patients presented with OAT were randomly allocated into four equal groups representing CoQ10, L-Carnitine, or combined therapy of both versus placebo. Our primary outcome was to monitor the improvement in semen parameters. The secondary outcomes were to evaluate the impact on the sperm DNA fragmentation (SDF) index and hormonal profile. Results: After 3 months of medical therapy, 174 patients completed the follow-up period. A highly statistically significant difference was monitored in the monotherapy and combination therapy in all semen parameters and SDF index compared to the baseline, while the placebo group failed to show any improvement. A rise in testosterone level and a decrease in luteinizing hormone were seen in the monotherapy and combination therapy, while no change was noted in the placebo group. Prolactin levels showed no change in all groups. Conclusion: Antioxidant therapy improves semen parameters in patients with OAT. A combination therapy of CoQ10 and L-carnitine results in a superior improvement in semen parameters compared to monotherapy in men with idiopathic OAT.
