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

Introduction: Preterm birth (PTB) affects 1 in 10 births in the USA and is associated with near-term and long-term health consequences. This study assesses social and geographical disparities in adverse birth outcomes and associated risk factors in Alaska. Methods: We examined birth records for 218 222 singleton live births in Alaska between 2000 and 2020. We described the distribution of PTB, very PTB, and low birth weight by geographical region, assessed risk factors for adverse birth outcomes, investigated how racial and ethnic differences in birth outcomes may be related to behavioural and social risk factors, and investigated how the unique transportation network in the state may affect adverse birth outcomes. Results: There was an increased risk of PTB among births to mothers over 35 years of age (adjusted OR, AOR: 1.26; 95% CI: 1.20, 1.33), with prepregnancy diabetes (AOR: 3.42; 95% CI: 3.00, 3.90) or hypertension (AOR: 2.28; 95% CI: 2.08, 2.51), who used tobacco during pregnancy (AOR: 1.33; 95% CI: 1.27, 1.40), and who received <11 prenatal care visits (AOR: 2.66; 95% CI: 2.56, 2.77). Racial disparities in PTB persisted after adjustment for behavioural and healthcare-related risk factors. Nearly 40% of births took place outside the mother's community of residence, and there was an increased risk of PTB associated with travelling for birth. Conclusions: PTB continues to be a persistent issue in Alaska, particularly among non-white mothers. Our findings regarding prenatal care utilisation, pre-existing health conditions, and tobacco use during pregnancy can support public health interventions to decrease the risk of adverse birth outcomes.
