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

backgroundMaternal exposure to unfavourable social conditions is associated with a higher rate of perinatal complications, such as placental vascular pathologies. A higher risk of preterm birth (PTB) has also been reported, and variations across studies and settings suggest that different patterns may be involved in this association.

objectiveTo assess the association between maternal social deprivation and PTB (overall and by phenotype).

methodsWe analysed 9365 patients included in the PreCARE cohort study. Four dimensions (social isolation, insecure housing, no income from work and absence of standard health insurance) defined maternal social deprivation (exposure). They were considered separately and combined into a social deprivation index (SDI). The associations between social deprivation and PTB <37 weeks (primary outcome) were analysed with univariable and multivariable log-binomial models (adjusted for maternal age, parity, education level and birthplace). Then we used multinomial analysis to examine the association with preterm birth phenotypes (secondary outcome): spontaneous labour, preterm prelabour rupture of membranes (PPROM) and placental vascular pathologies.

resultsIn all, 66.3%, 17.8%, 8.9% and 7.0% of patients had an SDI of 0, 1, 2 and 3, respectively. Social isolation affected 4.5% of the patients, insecure housing 15.5%, no income from work 15.6% and no standard health insurance 22.4%. Preterm birth complicated 7.0% of pregnancies (39.8% spontaneous labour, 28.3% PPROM, 21.8% placental vascular pathologies and 10.1% other phenotypes). Neither the univariable nor multivariable analyses found any association between social deprivation and the risk of preterm birth overall (SDI 1 versus 0: aRR 1.02, 95% confidence interval [CI] 0.83, 1.26; 2 versus 0: aRR 1.05, 95% CI 0.80, 1.38; 3 versus 0: aRR 0.92, 95% CI 0.66, 1.29) or its different phenotypes.

conclusionsIn the French PreCARE cohort, we observed no association between markers of social deprivation and the risk of preterm birth, regardless of phenotype.
