aCiPCA estimates are those using the maximal available run-in period method. bEstimates for population aged ≥40 years. In SIDIAP [8], AHCIP [9] and MSP [10], age-stratified incidence was available, allowing indirect standardization for comparison with CiPCA by using the age-stratified population size in CiPCA. The standardized overall estimates are presented in the parentheses.
