  1. (a) The SIR for general population is 1.00.
  2. (b) Observed number of cancer cases for population with type 2 diabetes after exclusion of cancers diagnosed within 1 year of cohort entry.
  3. (c) Observed number of cancer cases for population with type 2 diabetes using Registry of Catastrophic Illness Database
  4. SIRs were adjusted for covariates (insurance premium, urbanization degree of area registered for National Health Insurance program, and age).
  5. Bold type indicates that the 95% CI does not include 1.00. Abbreviations: CI confidence interval, O observed number of cancer cases, SIR standardized incidence ratio. #: per 1000 person-years; *: p < 0.05; **: p < 0.01; ***: p < 0.001.
