Impact of Maternal Age on the Foreign-Born Paradox.
Article in Journal of immigrant and minority health, 2021. 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
To examine the effect of maternal age on the risk of preterm birth and its phenotypes in foreign-born compared to native-born mothers. The 2014-2017 US Birth and Fetal Death data were analyzed (N = 14,867,880). Log-binomial regression models were used to estimate adjusted prevalence ratios (APR), quantifying the association between mother's nativity and preterm birth and its phenotypes, stratified by maternal age. Foreign-born mothers had a 13% lower probability of preterm birth compared to their native-born counterparts (APR, 0.87 [95% CI 0.86-0.87]). This protective effect persisted across all preterm phenotypes. Stratification by maternal age showed a slightly elevated risk in preterm and moderate-to-late preterm for adolescent mothers. Our study supports the existence of the "foreign-born paradox" whereby foreign-born mothers experienced lower levels of preterm birth despite the disadvantages of living in an alien socio-cultural environment. This favorable birth outcome was present primarily in foreign-born mothers aged ≥ 20 years.
