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

objectiveStudies of perinatal health outcomes in Canadian First Nations populations have largely focused on limited geographical areas and have been unable to examine outcomes by registered status and community residence. In this study, we compare rates of adverse birth outcomes among First Nations individuals living within vs. outside of First Nations communities and those with vs. without registered status.

methodsData included 13,506 singleton pregnancies from the 2006 Canadian Birth-Census Cohort. Outcomes examined included preterm birth (PTB), small- and large-for-gestational-age birth (SGA, LGA), stillbirth, overall infant mortality, and neonatal and postneonatal mortality. Risk ratios (RRs) were estimated with adjustment for maternal age, education, parity, and paternal education.

resultsMothers living in First Nations communities and those with status had elevated adjusted risks of LGA (RR for First Nations community residence = 1.22, 95% CI = 1.09-1.35; RR for status = 1.50, 95% CI = 1.16-1.93). Rates of SGA were significantly lower among mothers with status (adjusted RR = 0.62, 95% CI = 0.44-0.86). Rates of PTB did not vary substantially by residence or by status. Adjusted differences in fatal outcomes could not be estimated, owing to small cell sizes. However, mothers living in First Nations communities had higher crude rates of infant mortality (10.9 vs. 7.7 per 1000), particularly for neonatal mortality (6.1 vs. 2.9).

conclusionFuture investigations should explore risk factors, including food security and access to health care services, that may explain disparities in SGA and LGA by status and residence within First Nations populations.
