Mortality rate and standardized mortality ratio of childhood-onset type 1 diabetes according to incidentally detected non-acute-onset or acute-onset subtype, sex, and onset age: A cohort study

There was no difference in mortality or lifespan between sexes. Mortality and lifespan were not different between pre-and postpubertal onset. Mortality and lifespan were not different between subtypes of type 1 diabetes.mortality risk by subtype if there is a difference in the mortality rate among the subtypes.However, evidence of a fatal prognosis among patients with diabetes is scarce (2).In particular, the mortality associated with the acute-onset subtype versus the slowly progressive subtype of type 1 diabetes needs to be clarified because these two subtypes have different characteristics (2).It is impossible to detect slowly progressive subtype according to the recently issued criteria (1) using previous medical records.However, some cases are incidentally detected
