The impact of antioxidants on antioxidant capacity, DNA fragmentation, and chromatin quality in subfertile men: a randomized clinical trial study.
Trial report in Revista da Associacao Medica Brasileira (1992), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06042738 (The Impact of Antioxidant Food Supplementation on Seminal Antioxidant Capacity, Sperm DNA Fragmentation and Sperm Chromatin Quality in Subfertile Men With Oligoastenoteratozoospermia Randomized Clinical Trial), which is not on this 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.

Abstract
objectiveThis randomized clinical trial study aims to investigate the effects of antioxidant food supplementation on the total antioxidant capacity of seminal plasma, sperm DNA fragmentation, sperm chromatin quality, and semen parameters.
methodsIn this study, a total of 48 subfertile men with moderate physical activity were included. Group 1 was recommended to use the antioxidant supplements, while antioxidant food supplements were not given to Group 2. Total antioxidant capacity, sperm DNA fragmentation, sperm chromatin structure, hormone levels, physical activities, and semen parameters were evaluated before and after treatment. Total antioxidant capacity, sperm DNA fragmentation, and sperm chromatin structure were assessed using ELISA, transferase dUTP nick end labeling, and aniline blue staining, respectively.
resultsSperm DNA fragmentation (p=0.003) and histone/protamine ratio (p<0.001) were significantly decreased in the patients receiving antioxidant treatment. There was no statistical difference in the total antioxidant capacity values of the post-treatment groups.
conclusionAntioxidant therapy seems to improve sperm DNA fragmentation and histone/protamine ratios in subfertile patients. CLINICAL TRIAL REGISTRATION NUMBER: NCT06042738.
