aData are cumulative for two-year period (2001 and 2002)

bEnrollees in the dental maintenance services, other dental services, or no dental services received no periodontal services in 2001 and 2002.

cThe untransformed PMPMs for individuals are risk-adjusted using the average ERG score, and these are log-transformed for the t-test. The log transformations immediately precede the t-tests.

dThe log-transformed values are shown in parenthesis. The differences between group means were tested for statistical significance using the log transformed values of the individual total paid amounts
