Impacts of Paid Family Leave on Perinatal Health: A Nationwide Quasi-Experimental Study.
Article in Pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThe United States remains the only high-income nation without a national paid family leave (PFL) policy. It also has persistently high maternal and infant mortality rates. Understanding PFL impacts on perinatal health is critical. We determined the impact of state PFL policies on perinatal health, with additional focus on socioeconomic disparities.
methodsWe analyzed live singleton births using 2016 to 2022 birth certificate data (N = 11 452 411). We conducted a quasi-experimental analysis using heterogeneity-robust differences in differences, comparing pre-post trends in a comprehensive set of perinatal outcomes in jurisdictions with (Connecticut; Washington, DC; Massachusetts; New York; and Washington) and non-South states without PFL. Analyses were additionally stratified by maternal race and ethnicity, education, insurance, and Special Supplemental Nutrition Program for Women, Infants, and Children participation and adjusted for individual- and state-level time-varying covariates.
resultsHypertensive disorders of pregnancy risk decreased by 13% following PFL implementation, as did excess gestational weight gain. PFL implementation was associated with modest increases in small for gestational age (0.290 percentage points [pp]; 95% CI, -0.300 to -0.102), preterm birth (0.590 pp; 95% CI, 0.465-0.715), and lower mean birthweight (-5.205 g; 95% CI, -7.096 to -3.314). Socioeconomically disadvantaged subgroups saw higher risks of adverse birth outcomes but improved maternal outcomes.
conclusionsThis study adds to prior research that found that PFL is associated with improvements in parental health and breastfeeding in the United States. Our findings suggest that state PFL policies had mixed impacts on perinatal health; further investigation of policy parameters and mechanisms is warranted.
