Diabetes during pregnancy among Métis people in Alberta: a retrospective cohort study.
Article in CMAJ : Canadian Medical Association journal = journal de l'Association medicale canadienne, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundDiabetes in pregnancy is an important public health concern for Indigenous populations. We sought to evaluate the prevalence and outcomes of pre-existing and gestational diabetes among Métis pregnancies compared with other pregnancies in Alberta, Canada.
methodsWe conducted a retrospective cohort study using administrative health data from 2006 to 2016 and the Métis Nation of Alberta Identification Registry to compare the prevalence of pre-existing and gestational diabetes among all singleton Métis births with non-Métis births. We compared 10 maternal and neonatal outcomes using adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in multivariable analyses.
resultsThe study population included 7902 Métis and 471 886 non-Métis births. The age-standardized prevalence of pre-existing diabetes was 1.7% (95% CI 1.4%-2.1%) for Métis and 1.1% (95% CI 1.1%-1.2%) for non-Métis pregnancies. For gestational diabetes, the age-standardized prevalence was 6.3% (95% CI 5.6%-6.9%) for Métis and 5.4% (95% CI 5.3%-5.4%) for non-Métis pregnancies. After adjusting for parity, maternal weight, age, smoking during pregnancy and material and social deprivation, Métis pregnancies had 1.72 times higher prevalence of preexisting diabetes (adjusted OR 1.72, 95% CI 1.15-2.56) and 1.30 times higher prevalence of gestational diabetes (adjusted OR 1.30, 95% CI 1.08-1.57) than non-Métis pregnancies. Métis pregnancies with pre-existing diabetes had nearly 3 times the odds of developing preeclampsia (adjusted OR 2.96, 95% CI 1.27-6.90), while those with gestational diabetes had 48% higher odds of large-for-gestational-age infants (adjusted OR 1.48, 95% CI 1.00-2.19).
interpretationMétis pregnancies have an increased prevalence of pre-existing and gestational diabetes than non-Métis pregnancies and an elevated risk of some perinatal outcomes. Interventions to tackle these health inequities should address both physiologic and cultural dimensions of health, informed by Métis perspectives.
