  • OHA, oral hypoglycemic agent.

  • *Defined as the total number of person-years 12 months after cohort inception for partial and complete remission, and after 60 months for prolonged remission.

  • †Defined as 100% minus the cumulative survival probability calculated using the Kaplan-Meier method.
