Intergenerational risk of preterm birth in First Nations Australians: a population-based cohort study from the Northern Territory, Australia.
Article in BMC pregnancy and childbirth, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPTB increases the risk of health problems such as chronic renal disease and diabetes in later life and adverse impacts are inversely correlated with gestational age at birth. Rates of PTB in the Northern Territory (NT) of Australia are amongst the highest nationally and globally, with First Nations babies most affected. This study assessed the magnitude and potential drivers of intergenerational PTB recurrence in the NT.
methodsA retrospective intergenerational cohort study (1986-2017) was conducted amongst 5,366 mothers born singleton who had 9,571 singleton live births (7,673 First Nations, and 1,898 non-First Nations babies). Maternal and offspring PTB was categorised as early (< 34 weeks) and late (34-36 gestational weeks). Modified Poisson regression was used to estimate the relative risk (RR) of PTB associated with maternal PTB, adjusting for moderators such as receipt of antenatal care prior to the offspring PTB. Secondary analyses assessed the impact of additional adjustment for conditions with a familial component, or that PTB predisposes to, on the risk estimate. Mediation analysis assessed the degree of mediation of maternal-offspring PTB relationships by these conditions.
resultsOverall, First Nations women born preterm (< 37 weeks) had an increased risk of delivering before 37 gestational weeks (aRR 1.28; 95%CI 1.08, 1.51). Women born preterm had a higher risk of delivering early (< 34 gestational weeks) but not late preterm (34-36 weeks): the risk of early offspring PTB was increased amongst women themselves born early preterm (aRR 1.95, 95%CI 1.17, 3.24) or late preterm (aRR 1.41, 95%CI 1.01, 1.97). Adjustment for pre-eclampsia, intrauterine growth restriction, and hypertensive renal disease attenuated the observed intergenerational PTB associations. Mediation analysis suggested these conditions may mediate up to 26% of the observed intergenerational PTB recurrence. Similar trends were observed when first-time mothers were considered only. Maternal PTB status was not associated with PTB amongst non-First Nations women.
conclusionsFirst Nations women born preterm have an increased risk of early PTB. This association is in part driven by pre-eclampsia and hypertensive renal disease. Routine inquiry of maternal birth status may be a useful tool to identify NT First Nations women who may benefit from preventative measures.
