Prevalence and incidence of autism in children and adolescents in Manitoba, Canada: An updated estimate using population-based administrative health data from 2011 to 2022.

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
objectivesEstimates of autism prevalence are critical for informing evidence-based decisions, allocating resources, and developing effective strategies to support autistic individuals and their families. In Canada, such estimates remain limited, with the most recent population-based data on autism prevalence and incidence in Manitoba spanning 2004-2015, underscoring the need for more current data.
methodsWe used linked, whole-population administrative health and clinical data to develop a validated identification algorithm. We determined annual prevalence and incidence rates of autism among Manitoba children and adolescents aged 0-17 from 2011 to 2022, and conducted regression modelling to examine changes over time, adjusting for sex, geography, and socioeconomic variables.
resultsWe identified 9396 children and adolescents diagnosed with autism during the study period. The prevalence of autism diagnoses was 0.58% (95% CI 0.55-0.60) in 2011 and 1.67% (95% CI 1.63-1.72) in 2022. The incidence of autism diagnoses was 0.79/1000 (95% CI 0.69-0.90) in 2011 and 3.06/1000 (95% CI 2.87-3.27) in 2022. We found statistically significant year-over-year increases in both prevalence and incidence.
conclusionsIncreasing autism prevalence indicates a pressing public health need for sustained investment in specialized healthcare services and supports that promote the full inclusion of autistic people in society. Strengthening surveillance systems across Canada is essential for generating high-quality population-based data to inform policy development and resource allocation and ensuring the health and social needs of autistic people and their families are met.
