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

objectiveTo compare the incidence of breast feeding by day of week of birth.

designRetrospective database study using 16 508 records from the 2005 and 2010 Infant Feeding Surveys.

settingEngland and Wales, UK.

participantsMothers of a sample of births from among all registered births in the periods August-September 2005 and August-October 2010.

main outcome measureIncidence of breast feeding after birth.

resultsAmong babies of mothers who left full-time education aged 16 or under, the incidence of breast feeding was 6.7 percentage points lower (95% CI 1.4 to 12.1 percentage points) for those born on Saturdays than for those born on Mondays-Thursdays. No such differences by day of week of birth were observed among babies of mothers who left school aged 17 or over.

conclusionsBreastfeeding policy should take into account differences in breast feeding by day of week of birth, which are apparent among low-educated mothers. Further research is needed to ascertain the reason for this finding.
