Welles et al. respond to low vitamin D and cardiovascular disease

摘要

We appreciate the insightful commentary by Drs. Schneider and Michos (1). We have reanalyzed the data from our study (2) with adjustment for 3 categories of race/ethnicity: white, black, and other. The point estimates for the association between vitamin D and cardiovascular events were not appreciably altered by this substitution (Table 1). However, our participants were primarily white men; therefore, future studies in more racially diverse samples would be of interest to further explore racial differences, especially in light of the recent work by Powe et al. (3).
