1 · What the graph read from it

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.

2 · The registry

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

backgroundMost mothers in the UK are not meeting the breastfeeding recommendations set by the World Health Organisation (WHO, Breastfeeding - Recommendations. https://www.who.int/health-topics/breastfeeding#tab=tab_2 , 2023). Maternal obesity has variably been associated with lower initiation and shorter duration of breastfeeding, but few studies have examined the impact of maternal adiposity estimated from skinfold thicknesses.

aimTo investigate the relationship between maternal adiposity and breastfeeding initiation and duration.

methodsData from 2,873 mother-offspring pairs in the Southampton Women's Survey (SWS) mother-offspring cohort study were used to assess the relationship between a mother's adiposity and breastfeeding initiation and duration. The exposure variables were body mass index (BMI) and body fat percentage, calculated from 4-site skinfold thickness measurements measured prior to conception. The outcome variables were breastfeeding initiation and duration. All analyses were adjusted for confounders identified using a Directed Acyclic Graph.

resultsAfter adjustment for confounders, no associations were found between maternal BMI (RR 0.99 per 5 kg/m

conclusionsIn this study maternal adiposity had little impact on breastfeeding initiation but higher maternal adiposity was associated with shorter breastfeeding duration. This study suggests that more support should be given to mothers with overweight and obesity to promote longer duration of breastfeeding.
