Executive function development between ages 2 and 6 in children exposed to threatened preterm labor.

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
Children born after threatened preterm labor (TPL) are at increased risk for executive function (EF) difficulties, even when born at term. However, EF development in this population remains understudied, particularly regarding the role of gestational age and early psychosocial adversity. Prenatal stress (e.g., maternal anxiety at TPL diagnosis and trauma history) and postnatal environmental factors may contribute to variability in EF outcomes. In this prospective cohort study with a 6-year follow-up, EF was assessed at ages 2 and 6 using the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). The sample included 180 mother-child dyads: 120 children born after TPL (full-term n = 27, late-preterm n = 56, very-preterm n = 37) and 60 full-term controls. Bayesian mixed-effects models were used to examine associations between EF outcomes and gestational age group, time, and relevant prenatal and postnatal factors, including child sex, parental education, maternal trauma history, and maternal anxiety. The models showed a group × time interaction for global EF scores. At age 2, all TPL groups showed higher EF difficulty scores compared with controls, with the largest differences observed in the very-preterm group. Between ages 2 and 6, EF scores decreased in TPL groups relative to controls, indicating a greater reduction in EF difficulties over time, although patterns varied across EF domains. Higher maternal anxiety (prenatal and postnatal), greater maternal trauma exposure, and lower parental education were associated with higher EF difficulty scores, whereas female sex was associated with lower scores. Children born after TPL show early EF vulnerabilities across gestational ages, including those born at term. EF outcomes change across early childhood and are associated with both biological and environmental factors. These findings support the importance of early monitoring of children exposed to prenatal complications and highlight the role of perinatal maternal mental health and family context in early executive function development.
