Exploring the Association Between Parental Age and Autism Spectrum Disorder Risk in Qatar.

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
purposeAutism Spectrum Disorder (ASD) is a neurodevelopmental condition influenced by complex factors. Advanced parental age at childbirth has been associated with an increased likelihood of ASD. This study investigates the association between parental age and its correlation with ASD within the Qatari population, offering novel insights into an underrepresented region in autism research.
methodsA case-control design was utilized, including 970 ASD cases and 955 controls. Controls consisted of typically developing (TD) children and children with other neurodevelopmental disorders (NDDs). Statistical analyses included bivariate and multivariable logistic regression, with adjustment for potential confounders.
resultsMost ASD cases were male (79.4%), with a male-to-female ratio of approximately 3.85:1. Maternal age at childbirth was significantly higher among cases (30.14 ± 5.45 years; p < 0.001). A dose-dependent increase in the probability of ASD diagnosis was observed for mothers aged ≥ 30 years, with mothers aged 30–34 years having an aOR of 1.769 (95% CI: 1.320–2.372), 35–39 years an aOR of 2.046 (95% CI: 1.395–3.000), and the highest risk observed in mothers aged ≥ 40 years (aOR: 2.062, 95% CI: 1.184–3.593). Paternal age was significantly associated with ASD in unadjusted analyses but lost significance after adjusting for maternal age and other confounders.
conclusionThese findings highlight the need for broader awareness of factors linked to ASD and emphasize early identification and timely access to services.
