^1.Maximum lupus activity in pregnancy (PGA) was missing in 1 pregnancy.

^2.Includes any hospital visit (lupus-related and non-lupus related) for reason other than delivery. Lupus-related hospital visits included CNS lupus, lupus nephritis, pericarditis, serositis, hemolytic anemia, pancytopenia, and worsening pulmonary hypertension. Reasons for non-lupus-related hospital visits include chronic hypertension, asthma, infections, musculoskeletal chest pain, fetal heart block, preeclampsia rule-out, preterm labor rule-out, vaginal bleeding, and symptoms such as edema, nausea, vomiting, and abdominal cramping.

^3.Number of visits (mean ± S.D.) calculated out of all patients, including those who did not have a hospital visit during pregnancy.

^4.Length of stay calculated out of only patients who had a hospital visit. Hospital visits with length of stay < 1 day were considered as 0.5 days.
