Fig. 1. The total number of specialist anesthesiologists (A ), number of legal claims (B ), number of procedures (C ), and legal claim rate (D ) for each age group (less than 51: dashed , 51–64: dotted , 65 and older: solid ) are shown for each year between 1993 and 2002. Although the number of claims is much less for the older age group, the number of exposures is also much less. Therefore, the claim rate for the 65 and older age group is generally higher in each year.
