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 evaluate the longer-term impacts of the 2022 infant formula crisis on breastfeeding and mental health among historically socioeconomically disadvantaged groups.

methodsWe used 2017-2022 national serial cross-sectional data from the US Pregnancy Risk Assessment Monitoring System (N=193,383) to compare changes in breastfeeding initiation, breastfeeding duration, and postpartum depressive symptoms before (January 2017-January 2022) versus after (February-December 2022) the infant formula crisis. We compared pre-post trends among participants versus non-participants in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and by race and ethnicity, akin to a difference-in-differences study design.

resultsTrends (i.e., slopes) in the outcomes were similar among WIC participants and non-participants and by race and ethnicity before the formula crisis occurred. However, among WIC participants (relative to non-participants), the formula crisis was associated with increased breastfeeding initiation (3.2 percentage point [pp]; 95% CI: 2.4, 4.0) and duration (0.46 weeks; 95% CI: 0.24, 0.69), and no change in depressive symptoms. Among non-Hispanic Black respondents (relative to non-Hispanic White respondents), there was an increase in breastfeeding initiation (4.9pp; 95% CI: 3.7, 6.0), duration (0.61 weeks; 95% CI: 0.30, 0.92), and depressive symptoms (0.10-points; 95% CI: 0.02, 0.18).

conclusionThe formula crisis resulted in increased breastfeeding among historically marginalized groups, likely because it differentially disrupted access to formula among these populations. However, the concurrent rise in postpartum depressive symptoms suggests that this was a disproportionately stressful exposure for these individuals, highlighting the need for more comprehensive family support systems and policies in the postpartum period.
