Jun–Jun Yeh et al 20227	The colchicine cohort consists of patients with diabetes mellitus who received colchicine treatment.	The non-colchicine cohort consisted of patients with diabetes mellitus who did not receive colchicine treatment.	The duration of treatment varied depending on the patient's use of colchicine. The study analysed the effects of colchicine use with a cumulative daily defined dose (cDDD) of >14 and duration of >28 days, as well as with a cDDD of >150 and a duration of >360 days.	The primary outcome was the incidence of stroke, including ischemic stroke and hemorrhagic stroke, between the colchicine cohort and the non-colchicine cohort.	The study also analysed the incidence of stroke, ischemic stroke, and hemorrhagic stroke in patients who received different durations and doses of colchicine treatment. The subdistribution hazard model was used to examine the competing risk.
