Sex differences in 5-year incidence and prevalence of physical illnesses following early childhood autism diagnosis.
Article in JCPP advances, 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
Background: Sex differences in the clinical presentation of autism are established, but evidence on early-life co-occurring physical illnesses in early-diagnosed autistic individuals is scarce. This nationwide cohort study examined sex-stratified incidence of physical illnesses within 5 years after autism spectrum disorder (ASD) diagnosis in children ≤5 years. Methods: Using Taiwan's National Health Insurance Research Database (2000-2019), we identified 36,656 autistic males and 9024 autistic females newly diagnosed before age 6 and followed for five years. Adjusted odds ratios and hazard ratios for physical illnesses were estimated via multivariate logistic and Cox regression, controlling for demographic, clinical, and healthcare utilization factors. Analyses were stratified by intellectual disability status. Results: Within 5 years following an ASD diagnosis, autistic females exhibited higher incidences of cardiovascular diseases, cerebrovascular diseases, epilepsy, and irritable bowel syndrome, with generally modest to moderate effect sizes (approximately 1.3-2.3). In contrast, autistic males consistently demonstrated a higher risk of asthma. Prevalence analyses revealed similar patterns. Stratified analyses further indicated that, among children without intellectual disabilities, autistic females remained at elevated risks for cardiovascular diseases and epilepsy, with effect sizes ranging from approximately 1.44 to 2.86. Additional increased risks of hyperlipidemia and atopic dermatitis were also observed in autistic females, whereas autistic males continued to show higher risks of asthma and diabetes mellitus. Conclusion: Autistic females in early childhood face greater cardiometabolic and neurological burdens, while males are more prone to respiratory and metabolic conditions. These sex- and cognition-specific risk profiles support tailored screening-cardiovascular/metabolic monitoring for females and respiratory disease prevention for males-to inform clinical care and health policy.
