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: Alopecia areata (AA) has been associated with adverse pregnancy outcomes, but its relationship with infertility remains poorly characterized. Given the prevalence and psychosocial impact of infertility and the reproductive implications of systemic AA therapies, we examined for potential associations between AA and infertility. Methods: A retrospective cohort study was conducted using the TriNetX research network, querying for female patients aged 18-45 years with AA and matched controls. Reproductive outcomes <10-years of diagnosis were compared between cohorts, excluding patients with pre-existing outcomes. AA patients were additionally compared with matched infertile controls. Sex hormone levels were analyzed using Results: A total of 31,404 AA patients and 31,404 matched controls were included. AA was associated with increased risk of infertility (risk ratio [RR] = 1.21, 95% confidence interval [CI]: 1.09-1.35) and decreased likelihood of pregnancy (RR = 0.78, 95% CI: 0.73-0.82) and in vitro fertilization (IVF) utilization (RR = 0.71, 95% CI: 0.52-0.99). Compared with infertile controls, AA patients had significantly lower IVF use (0.17% vs. 5.04%) and pregnancy rates (6.50% vs. 19.45%) (both Conclusion: AA was associated with increased infertility risk and reduced reproductive outcomes, suggesting broader reproductive implications beyond infertility alone. Multidisciplinary counseling and prospective studies incorporating reproductive intentions are warranted.
