Ethnic differences in postmaturity syndrome in newborns. Reflections on different durations of gestation.
Observational study in The journal of maternal-fetal & neonatal medicine : the official journal of the European Association of Perinatal Medicine, the Federation of Asia and Oceania Perinatal Societies, the International Society of Perinatal Obstetricians, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 describe the prevalence, by weeks of gestation, of post-maturity signs in newborns by ethnic origins. STUDY
designObservational cohort study (2001-2018), of all consecutive singleton births delivered at Center Hospitalier Universitaire Hospitalier Sud Reunion's maternity (Reunion Island, French overseas department, Indian Ocean). The presence of clinical post-maturity signs was recorded by a week of gestation using Clifford's clinical post-maturity signs in newborns (desquamation, dry skin, wrinkling fingers and cracked skin).
resultsOf the 67,463 singleton births during the period, 58,503 newborns were from Reunion island, 5756 were of European origin (mainland France), and 4061 newborns from the archipelago of Comoros (North of Madagascar). Mean duration of gestation was 276 days in Caucasian women, 272 days in Comorian mothers and 273 days in Reunionese (
conclusionAmong African (Black) pregnancies, duration of gestation was approximately 7 days shorter than in Caucasian (White) pregnancies. In the Reunionese intermixed population and Comorians, the gestation was shorter by 3-4 days. Black newborns presented severe clinical post-maturity signs beginning around 40 weeks and 4-6 days, while it was 1 week later in white infants. Consequences of these differences, with respect to clinical outcomes, are discussed.
