Categorical variables listed as n (%); continuous variables listed as median (IQR).
↵* N = 46; 2 pregnancies ended in nonlive births and 2 pregnancies had unknown neonatal outcomes.
↵** Comparing ≤ 100 ng/ml vs > 100 ng/ml.
↵*** Comparing ≤ 100 ng/ml vs 101–500 ng/ml vs > 500 ng/l. Values in bold face are statistically significant. HCQ: hydroxychloroquine; GA: gestational age at birth; SLE: systemic lupus erythematosus; IQR: interquartile range.
