Notes: Values are given as median (range) or number (percentage).N = 1 missing for gestational hypertension from the Mycoplasma genitalium (MG)–negative group.
N = 1 missing for pre-eclampsia from the MG-negative group.
N = 1 missing for severe pre-eclampsia from the MG-negative group.
N = 1 missing for gestational age at delivery from the MG-negative group.
N = 2 missing for small for gestational age from the MG-negative group.
N = 2 missing for fetal growth restriction from the MG-negative group.
By Pearson chi-square, Fisher exact, or Wilcoxon rank-sum (Mann–Whitney) test, as appropriate.
Preterm birth defined as a livebirth before <37 weeks of gestation but after >20 weeks of gestation; small for gestational age defined as birth weight < 10th percentile for gestational age; fetal growth restriction defined as an estimated fetal weight < 10th percentile.
