Recruitment and retention of participants with obesity into a longitudinal birth cohort: the Breastfeeding and Early Child Health (BEACH) study.
Article in International journal of obesity (2005), 2025. 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
backgroundThe study aimed to evaluate how maternal pre-pregnant body mass index (BMI) impacts participant recruitment and retention.
methodsParticipants were enrolled in a longitudinal study between 30 and 36 weeks of pregnancy as having normal weight (pre-pregnant BMI ≥ 18.5 and <25 kg/m
resultsRecruitment yielded 2770 total prospective participants. After screening, 141 individuals were eligible, 83 consented, and 60 completed the study. Facebook was the most successful method for identifying eligible pregnant patients with obesity, while a higher percentage of participants recruited through word-of-mouth and flyers consented to the study. Pre-pregnant BMI was significantly associated with the stage of recruitment completed by the participant (p = 0.04), whereby individuals eligible for the study with obesity were less likely to consent and complete study visits.
conclusionWe demonstrated that maternal obesity was significantly associated with enrollment outcomes in a longitudinal birth cohort study. This study showed that pre-pregnancy BMI influenced study participation. Therefore, tailored recruitment strategies to enhance the recruitment and enrollment of individuals with obesity in maternal-infant health research may be necessary.
