Contribution of previable births to infant mortality rate racial disparity in the United States.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo quantify racial differences in contribution of previable live births (<20 weeks gestational age (GA)) to United States (US) Infant Mortality Rates (IMR).
methodsPopulation-based retrospective cohort of US live births (2007-14) using CDC WONDER database stratified by maternal race/ethnicity. We compared the contribution of previable births to IMR and calculated modified IMRs (≥20 weeks GA) excluding previable live births in each group. Contingency tables and chi-square calculations were performed to detect differences between groups.
resultsPreviable deaths represented 4.1%, 7.7%, and 5.0% of total deaths for nonHispanic white, nonHispanic black, and Hispanic, respectively. Previable contribution to total IMR are 0.21, 0.89, and 0.26 per 1000 live births (P < 0.0001). Modified IMRs are 4.98, 10.85, and 4.69 deaths per 1000 live births.
conclusionIMR standardization with a minimum GA may obscure the disproportionate contribution of previable births to IMRs among the black population, which has the largest proportion of previable births.
