Male Sex is an Inherent Risk Factor for Basal Cell Carcinoma

Figure 1

Male to female ratio of BCC incidence rates as a function of age. Each point represents ratio determination from paired data, i.e., for the same age period within each study. The best fit Loess line is shown (with Epanikov kernel at 50%). It crosses with the RR = 1 line of equal incidence rates of males and females (red line) at the age between 45 and 50 years.
