Adjusted Risk Ratios of Obstetric Outcomes by (A) Epilepsy and (B) Multiple Sclerosis Defined in the Delivery and Pre-Delivery Interval (Truven Health MarketScan® Commercial Claims and Encounters Database, 2011-2014, USA, N=909,065). Risk ratios adjusted for maternal age, region (Northeast, Midwest/North Central, South, and West) and year of delivery. Pre-Delivery = Pre-existing condition recorded on at least two days in the 270 days before delivery until, and including, the delivery date (and at least one anti-convulsant prescription for epilepsy). Delivery = Pre-existing condition recorded on at least one day during the delivery hospitalization. RR= risk ratio, LCI= lower confidence interval, UCI= upper confidence interval.
