  2. bEnrollees in the dental maintenance services, other dental services, or no dental services received no periodontal services in 2001 and 2002.
  3. 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.
  4. 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
