Determinants of infant behavior and growth in breastfed late preterm and early term infants: a secondary data analysis.
Article in World journal of pediatrics : WJP, 2023. 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
backgroundLate preterm and early term infants are at increased risk of poor growth, behavioral problems, and developmental delays. This study aimed to investigate the impact of maternal and infant characteristics, feeding practices, and breastmilk composition on infant behavior following late preterm and early term delivery, and to evaluate the association between infant behavior and growth.
methodsData from 52 Chinese mothers and their late preterm/early term infants participating in the Breastfeed a Better Youngster study were used. Maternal and infant characteristics were collected using questionnaires at 1 week postpartum. Breastmilk macronutrient content was measured using a human milk analyzer, and infant behavior was assessed using a 3-day infant behavior diary at 8 weeks postpartum. Feeding practices were collected at both time points using questionnaires. Multivariate models were used to assess associations between potential predictors and infant behavior and between infant behavior and growth.
resultsExclusive breastfeeding was associated with greater sleep duration (P = 0.02) and shorter crying duration (P = 0.01). Mothers with a vocational education reported greater distress duration (P = 0.006). Greater colic duration was associated with higher maternal annual income (P = 0.004). There was no significant association between infant behavior and growth (all P > 0.05).
conclusionsExclusive breastfeeding might promote more favorable infant behaviors in late preterm/early term infants, while the development of infant distress behaviors was associated with some maternal characteristics (maternal education and annual income). However, due to the limitations of diary methods, determinants of infant behavior should ideally be assessed using more objective measures in larger samples.
