Models using only complete cases had the same results—2M: estimate = 0.8463, p value = 0.0088; 6M and 12M ns
^aFollow-up windows included a ± 30 day window; e.g., 2 months post index = 60 ± 30d post index, 6 months = 183 ± 30d post index, 12 months = 365 ± 30d post index
^bOther race was created due to small n's, includes Native American/Alaskan Native, Native Hawaiian/Pacific Islander, Multiracial and Unknown race
