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
purposeTo investigate the relationship between polyunsaturated fatty acids and biochemical hypogonadism in aging males with a cross-sectional NHANES data.
methodsA total of 1165 men aged ≥ 65 years old, who had complete data on total testosterone levels and erythrocyte membrane fatty acid composition measurements, were included from the National Health and Nutrition Examination Survey (NHANES) 2021-2023 dataset. Biochemical hypogonadism was defined as total testosterone ≤ 300 ng/dL. Age, body mass index (BMI), waist circumference, diabetes mellitus (DM), fatty acid enzyme activities, HDL, LDL, triglycerides, and total cholesterol were also recorded.
resultsA total of 1,165 men were analyzed, of whom 859 had complete total testosterone data. In multivariate logistic regression analysis using continuous variables, higher arachidonic acid levels were independently associated with lower odds of biochemical hypogonadism (OR 0.80, 95% CI 0.66-0.97, p = 0.026). Triglyceride levels (OR 1.005, 95% CI 1.001-1.009, p = 0.006) and waist circumference (OR 1.037, 95% CI 1.019-1.056, p < 0.001) were positively associated with biochemical hypogonadism. Diabetes mellitus showed a borderline association with hypogonadism but did not reach statistical significance after adjustment (OR 1.54, 95% CI 0.93-2.56, p = 0.09). HDL cholesterol, palmitoleic acid, docosahexaenoic acid, and linoleic acid were associated with biochemical hypogonadism in univariate analysis but did not remain significant after multivariate adjustment.
conclusionArachidonic acid (AA), a component of the omega-6 fatty acid pathway, levels were independently associated with lower odds of biochemical hypogonadism. whereas waist circumference, diabetes mellitus and triglycerides were associated with biochemical hypogonadism.
