The relationship between dietary inflammatory indices and male infertility: a cross-sectional study.
Article in BMC research notes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveInflammation is the body's defense mechanism against harmful external stimuli, which can contribute to disorders such as infertility. The purpose of this research was to assess the relationship among the Dietary Inflammatory Index (DII), Empirical Dietary Inflammatory Pattern (EDIP), and Dietary Inflammation Score (DIS) in relation to the odds of infertility in Iranian men.
resultsWe observed higher odds of abnormal sperm concentration in both the second tertile (odds ratio (OR) = 3.198, 95% confidence interval (CI): 1.189-8.599) and the last tertile of DII (OR = 3.718, 95% CI: 1.373-10.046) when compared to the first tertile in the adjusted model. However, for other sperm quality parameters, no significant associations were found in the adjusted model (P > 0.05 for all). The findings of the present research indicated that following a pro-inflammatory dietary pattern, as reflected by a greater DII score, negatively impacts sperm quality parameters, including sperm concentration. Longitudinal studies are needed to better clarify the relationship between dietary inflammatory indices and male infertility.
