Observational study in American journal of public health, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 1 of them a synthesis that pooled it.

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

objectivesTo assess how the 2012 Affordable Care Act (ACA) policy change, which required most private health insurance plans to cover lactation-support services and breastfeeding equipment (without cost-sharing), affected breastfeeding outcomes.

methodsWe used a regression-adjusted difference-in-differences approach with cross-sectional observational data from the US National Immunization Survey from 2008 to 2014 to estimate the effect of the ACA policy change on breastfeeding outcomes, including initiation, duration, and age at first formula feeding. The sample included children aged 19 to 23 months covered by private health insurance or Medicaid.

resultsThe ACA policy change was associated with an increase in breastfeeding duration by 10% (0.57 months; P = .007) and duration of exclusive breastfeeding by 21% (0.74 months; P = .001) among the eligible population. Results indicate no significant effects on breastfeeding initiation and age at first formula feeding.

conclusionsReducing barriers to receiving support services and breastfeeding equipment shows promise as part of a broader effort to encourage breastfeeding, particularly the duration of breastfeeding and the amount of time before formula supplementation.
