The "Other" race category on birth certificates and its impact on analyses of preterm birth inequity.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveNot all individuals self-identify with race categories on birth certificates, selecting "Other" and writing in identities. Our hypothesis was that curating write-in responses in the "Other" race category would contribute to understanding preterm birth inequities.
methodsWe analyzed Pennsylvania birth certificates (2006-2014). Two independent coders reviewed each write-in response among those who selected "Other" race. We compared preterm birth rates across subpopulations within "Other" race category using a Monte Carlo simulated Chi-square test.
resultsAmong 1,196,125 singleton births, 72,891 (6.1%) exclusively selected "Other" race; Hispanic more often than non-Hispanic individuals (54.5% vs 0.7%), p < 0.0001). Only 545 (0.8%) of Hispanic individuals wrote in responses aligned with preestablished race categories compared to 2,601 (33.2%) of non-Hispanic individuals. Preterm birth rates varied significantly across identities within the "Other" group (P < 0.001).
conclusionUtilizing combinations of self-identified race, ethnicity, and continental origin may facilitate public health efforts focused on birth outcome equity.
