Social support modifies the association between pre-pregnancy body mass index and breastfeeding initiation in Brazil.
Article in PloS one, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundMany biological, social and cultural barriers for suboptimal breastfeeding practices have been identified in literature. Among these, excessive pre-pregnancy weight has been identified as a risk factor for not initiating breastfeeding early. Social support, coming from social networks (e.g. a partner, family or friends) or health care providers, has been positively associated with breastfeeding. This study aimed to examine the association between pre-pregnancy excessive weight and breastfeeding within the first hour after birth and if social support modifies this association.
designNational population-based study conducted with 21,086 postpartum women from February 1, 2011 to October 31, 2012 in 266 hospitals from all five regions of Brazil. Social support was defined as having a companion at the hospital. Main effects and interactions were tested with multivariable regression analyses.
resultsMultivariate regression analyses indicated that class I and class II obese women had lower odds of breastfeeding within the first hour when a companion was not present (AOR = 0.59, 95% CI 0.42-0.82 and AOR = 0.59, 95% CI 0.36-0.97, respectively), but there was no association when the companion was present. Among overweight and obese women, the predicted probability of breastfeeding within the first hour was lower for those without a companion. This association was not found among those with normal pre-pregnancy BMI.
conclusionsSocial support modifies the relationship between pre-gestational BMI and breastfeeding initiation among women who are overweight or obese, specifically it reduces the risk of delayed breastfeeding initiation.
