A Protocol to Assess Adult Outcomes at 30 Years Following Preterm Birth.
Article in Nursing research. 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
backgroundAmong the most intense adversity experiences for infants is premature birth. Early birth marks the beginning of a life course that broadly affects families, healthcare, education, social systems, and the survivors themselves. For many, the transition to adulthood is challenging and often hampered by cognitive, physical and mental health, and motor and independence difficulties.
objectivesThe aim of this study was to share a comprehensive protocol of a 10th follow-up study of premature infants in their 30s. The protocol accounts for stress during the neonatal period, the cumulative context (risk and protection) of development, biological and epigenetic mechanisms, and individual resilience.
methodsThe prospective, five-group longitudinal design includes 215 term-born and preterm-born individuals with various neonatal morbidities at ages 30-35 years. Adult outcomes include health, adaptive, executive function, work, and social competence. Novel measures are four system indicators of allostatic load (AL) and epigenetics. Contextual measures include socioeconomic risk and individual resilience. All measures were selected based on coherence with constructs of the scientific aims, strong psychometrics, continuity for repeated measures, and minimal subject burden. Objective assessments include body composition imaging, exercise testing, blood and saliva collection, and actigraphy. The two-phase protocol takes approximately 8 hours. DISCUSSION: After an 11-month COVID-19 pause, participant response has been strong. As of May 2022, 75 participants have completed the full protocol, and 99 have consented to participate. When socioeconomic risk is controlled, we hypothesize that life course trajectories in physical and psychological health, adaptive function, and executive function will differ between term and preterm neonatal morbidity groups. AL will vary across groups and contribute to outcomes. We expect proximal protection and resilience to mediate the cumulative medical and socioeconomic risk and AL. Epigenome-wide DNA methylation, with estimates of age acceleration, will be examined across groups and explored in longitudinal associations with medical risk, socioeconomic status, and protection. To our knowledge, this is the only U.S. study of premature infants aged 30-35 years. With millions of preterm-born individuals reaching adulthood, the protocol incorporates molecular and genetic biomarkers in a life course developmental examination to inform the timing and content of interventions.
