Legend: Training set population has been divided into six strata, based on the number of chronic diseases present. First column presents stratum. Second column gives population size. Third column gives total number of pharmaceutical groups utilized. Pharmaceutical groups have been defined in terms of an ATC 4 position code: A01A, A02A, etc. Last column gives average utilization in stratum.
