Demographic information for all 128 patients, along with their skin tone measurements, were grouped by race. The group “Other” contains patients who self-identify as Asian (n = 5), American Indian/Alaskan natives (n = 6), more than two races (n = 2), and unknown race (n = 2). Among the eight Skin Tone Scales, the Monk Scale, Fitzpatrick scale, Von Luschan scale, and Delfin Melanin Index are ordered numerically ascending from light to dark, the other ones are ascending. Detailed descriptions of each skin tone variable are shown in Supplemental Table 2 (http://links.lww.com/CCX/B379).
