Relationship between RTS-score and other methods for the measurement of sun sensitivity. The box plots show the distributions of the RTS-score. A: RTS-score by four categories of hair color: 1: red, red brown; 2: light blond, blond; 3: dark blond, brown; 4: black. (n = 655). B: RTS-score by skin type classes of Fitzpatrick, pigmentation after repeated exposure (n = 617). C: RTS-score by skin type classes of Uter (n = 655). D: RTS-score by SSSE-score after categorization of SSSE-score in four groups: 1: SSSE ≤ 2.5; 2: > 2.5 ≥ 5.0; 3: > 5.0 ≤ 7.5; 4: > 7.5 (n = 655).
