The role of body composition, irisin, and FABP4 levels in adolescent girls with polycystic ovary syndrome.
Article in BMC endocrine disorders, 2026. 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
objectiveThis study aimed to investigate the relationship between body composition parameters and serum irisin and FABP4 levels in adolescent girls with polycystic ovary syndrome (PCOS).
methodsA total of 123 participants (54 with PCOS and 69 controls) were included in this cross-sectional study. Biochemical and hormonal parameters were assessed, and body composition was evaluated using bioelectrical impedance analysis (BIA). Multivariable logistic regression analysis was performed to identify factors associated with PCOS.
resultsCompared with controls, the PCOS group showed significantly higher levels of total testosterone and luteinizing hormone. Muscle mass index was also higher in the PCOS group, whereas other body composition parameters did not differ significantly between groups. In multivariable logistic regression analysis, total testosterone and Luteinizing hormone emerged as independent predictor of PCOS (OR = 1.089, 95% CI: 1.050-1.128, p < 0.001), (OR = 1.084, 95% CI: 1.003-1.172, p = 0.041) relatively. While BMI Serum irisin and FABP4 was not independently associated with PCOS.
conclusionIn adolescent PCOS, hyperandrogenemia, particularly total testosterone, remains the strongest independent correlate of disease status. In contrast, circulating irisin and FABP4 do not appear to provide additional independent discriminatory value. These findings should be interpreted within the limitations of a cross-sectional design, and further prospective studies are warranted. CLINICAL TRIAL NUMBER: Not applicable.
