1 · What the graph read from it

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.

2 · The registry

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

Objectives: To examine the relationship between immigration and autism in Manitoba, Canada, using population-based data. Methods: We linked Manitoba's Rehabilitation Centre for Children clinical registry (May 2016-December 2022), the province's primary and only publicly funded autism evaluation site for children ≤6 years, with an official immigration registry. We estimated incidence of autism and adjusted relative risks (aRR) with 95% confidence intervals (CI) across subgroups defined by child and parent immigration status. Results: A total of 217,811 children aged 18 months to 6 years resided in Manitoba during the study period and met inclusion criteria. Among 2408 children diagnosed with autism, 1136 (47%) had at least one immigrant parent. Compared with Canadian-born children of nonimmigrant parents, autism risk was highest among Canadian-born children of at least one immigrant parent (aRR: 2.29; 95% CI: 2.09-2.51), followed by immigrant children of at least one immigrant parent (aRR: 1.72; 95% CI: 1.42-2.09). Maternal length of stay in Canada and refugee status was not associated with autism risk. In secondary analysis examining parental contribution to likelihood of autism, compared with Canadian children of two nonimmigrant parents, likelihood of autism diagnosis was higher among children in all parental immigration categories, but highest when both the mother and the father were immigrants (aRR: 3.08, 95% CI: 2.62-3.62). Conclusion: Children of immigrant families in Manitoba had higher rates of autism. Additional studies are warranted to assess whether similar results occur in other Canadian jurisdictions, and to investigate possible underlying factors behind this association.
