All values are crude odds ratios (95% confidence intervals) unless otherwise stated. RA: rheumatoid arthritis; SLE: systemic lupus erythematosus; OR odds ratio; CI: confidence interval; SGA: small for gestational age; IUGR: intrauterine growth restriction; NR: not reported. *All pregnancy-related hypertensive disorders. In the studies by Clowse, Reed, Lin, Wallenius, Nørgaard, and Wolfberg odds ratios for preeclampsia are reported. †Clowse reports preterm labor. Nørgaard reports prematurity as 32–36 weeks gestation. ‡All report small for gestational age, except Chakravarty and Clowse which report intrauterine growth restriction. §Adjusted for dysfunctional labor (including uterine inertia, malpresentation, or obstruction) and previous cesarean section. ||Adjusted for instrumentation and caesarean section. ¶Adjusted for maternal hypertension. **Adjusted for comorbidities, pregnancy complications, and medical computations. ††Relative risk calculated from odds ratio; adjusted for age, smoking, year. ‡‡Adjusted for age. |
