Exploring Parental Factors in Autism Spectrum Disorder Risk: A Case-Control Study.
Article in Maternal and child health journal, 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
backgroundAutism spectrum disorder (ASD) is a complex neurodevelopmental condition. Diagnosis is based on developmental history and behavioral observation. Parental age has been identified as a potential risk factor for ASD.
objectivesThis study aimed to assess the association between maternal age, paternal age, parental education level, smoking history, and ASD risk.
methodsThis case-control study included 154 individuals with ASD and 335 controls. Demographic, clinical, and familial data were collected through structured questionnaires and interviews. Statistical analysis included descriptive statistics and chi-square tests for categorical variables. RESULTS AND DISCUSSION: A total of 489 participants were included (154 ASD cases and 335 controls). The ASD group was predominantly male (77%), compared with the control group (68%). Mothers in both groups most commonly held a bachelor's degree (40%), while fathers showed more variable educational backgrounds. A family history of ASD was significantly more frequent in the ASD group (23%) compared with controls (5.4%), whereas a family history of psychiatric disorders showed no significant difference (15% vs. 11%). NICU admission (11% vs. 2.4%) and preterm delivery (7.3% vs. 1.8%) were more common in the ASD group. In multivariable analysis, paternal age (adjusted OR = 1.08, 95% CI: 1.03-1.14), maternal age (adjusted OR = 1.09, 95% CI: 1.03-1.15), male sex (adjusted OR = 4.13, 95% CI: 2.38-7.16), and family history of ASD (adjusted OR = 2.40, 95% CI: 1.09-5.30) were independently associated with ASD.
conclusionsASD risk was independently associated with parental age, male sex, and family history of ASD, highlighting the role of genetic and demographic factors. Prospective longitudinal studies are needed to further clarify ASD risk trajectories.
