Group 1 = SDF; Group 2 = SDF; Group 3 = AgF; Group 4 = AgF&KI.
b
P= <0.001; χ2 test for differences among groups within the same column.
c
analysis of transition of a lesion from one colour category to a darker category was performed for lesions that were not classified as being a black colour at baseline (n = 2334).
