Pregnancy complications, treatment, and prognosis: Active PRL vs. s-PRL.

Data are depicted as n (%).
PRL: pregnancy-related lupus.
a-PRL: active lupus during pregnancy and puerperium.
n-PRL: new-onset lupus during pregnancy and puerperium.
f-PRL: flare of established lupus during pregnancy and puerperium.
s-PRL: established lupus remained stable during pregnancy and puerperium.
Spontaneous abortion: spontaneous fetal loss before 28 weeks of gestation.
Stillbirth: intrauterine fetal demise after 28 weeks of gestation.
Neonatal death: live infant dying within 28 days after delivery.
Induced abortion: voluntarily induced termination of pregnancy.
