The criteria in each group are given a point and then multiplied by cofactors to determine the total dermatoscopy score (TDS). A score × 1.3 + B score × 0.1 + C score × 0.5 + D score × 0.5 = TDS. TDS greater than 5.45 is highly suggestive of a melanoma. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - dermatology.mhmedical.com/content.aspx?aid=1175416561 ER -
