Anesthesia-related adverse events during cesarean delivery in New York state between 2003 and 2012. The P value is from a multivariate logistic regression adjusted for year and Charlson and Bateman comorbidities indexes.17–19 The legend indicates the percent change from 2003 to 2012 (95% CI). (A) Overall crude rate of anesthesia-related adverse events. The vertical lines indicate the exact 95% CI. The subscript numbers indicate the number of events for the corresponding year. (B) Crude rate of major specific anesthesia-related adverse events. Major adverse events are defined as events with a risk of death or cardiac arrest greater than 1%. NA indicates that the percent change for this adverse event cannot be calculated because of the absence of events in 2003.
