Adjusted odds ratios for death among foetuses alive at mother's admission for delivery among the Swedish healthcare regions (reference = Stockholm region), according to the time of death. Odds ratios are adjusted for gestational age (weeks) and (weeks²), multiple births (yes/no), gender and birthweight standard deviation score ¹⁶. Adjusted proportion of variation that can be explained by the regional difference (R²): stillbirth: 22–24 weeks, 0.05; 22–26 weeks, 0.01. Perinatal death: 22–24 weeks, 0.10; 22–26 weeks 0.02. Death before 365 days: 22–24 weeks, 0.06; 22–26 weeks, 0.01.
