Associations of Maternal Trait Anger Expression and Lifetime Traumatic and Non-traumatic Experiences with Preterm Birth.
Article in Maternal and child health journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled 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.
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
objectivesMost studies examining psychosocial factors contributing to preterm birth (PTB) have focused on negative life events. Studies examining the influence of negative emotion, in particular maternal anger, remain sparse. We examined associations of maternal trait anger expression and lifetime traumatic and non-traumatic experiences with the risk of PTB.
methodsMother-newborn pairs were enrolled in the PRogramming of Intergenerational Stress Mechanisms pregnancy cohort based in Boston and New York City. Women completed the State-Trait Anger Expression Inventory-2 (STAXI-2), Life Stressor Checklist-Revised (LSC-R), and Childhood Trauma Questionnaire (CTQ) in pregnancy. We used modified Poisson regression to estimate the relative risk (RR) of PTB (1) in relation to continuous STAXI-2 Anger Expression-In (AX-I) and Anger Expression-Out (AX-O) subscales, (2) in relation to continuous LSC-R scores, and (3) between women who did versus did not experience childhood sexual, emotional, and/or physical abuse in six separate models. We also examined interactions between maternal anger expression and lifetime stress/childhood trauma.
resultsYounger, single, minority women had higher outward anger expression and inward anger suppression. AX-I and AX-O scores were higher among women who experienced abuse in childhood and who had higher lifetime stress. Maternal lifetime stress, outward anger expression, and inward anger suppression were associated with an increased risk of PTB in separate models; however, stress, trauma and anger did not interact to further increase the risk of PTB. CONCLUSIONS FOR PRACTICE: Higher anger expression and higher lifetime stress experiences were associated with an increased risk of PTB among a racially and ethnically diverse sample of pregnant women.
