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

objectivesEconomic class immigrants to Canada tend to have better health outcomes than other immigrant groups. However, variation may exist even within this population.

methodsWe conducted a retrospective cohort analysis of data from the Migrant Maternal and Infant Morbidity and Mortality (MMIMM) dataset, which linked Canadian birth and infant death records (1993-2017) with maternal immigration records (1952-2017). All singleton births to economic class immigrant women at least 18 years of age at immigration were analyzed. Women were classified as principal applicants (PA), non-principal applicants (NPA), or former live-in caregivers (LIC); all analyses were stratified by marital status at landing. Outcomes examined included preterm birth (PTB), small- and large-for-gestational-age birth (SGA and LGA, respectively), stillbirth, and infant mortality. Risk ratios for adverse outcomes by PA and former LIC status were estimated with adjustment for parental, birth, and immigration characteristics.

resultsThe cohort included 490,310 births (165,850 births to PAs, 267,200 to NPAs, 57,160 to former LICs). In adjusted analyses, among women who were single at landing, NPA had slightly lower rates of LGA (fully adjusted risk ratio (aRR) = 0.92, 95% CI 0.87-0.98) and stillbirth (aRR = 0.72, 95% CI 0.53-0.97) compared to PA, and former LICs had slightly elevated rates of PTB (aRR 1.05, 95% CI 1.00-1.11) and SGA (1.05, 95% CI 1.01-1.10).

conclusionThese findings add to existing literature highlighting the vulnerability of live-in caregivers in Canada while shedding light on possible differences between principal and non-principal applicants.
