Figure 2 Second-to-fourth digit ratios (2D: 4D) of different sexes distributed in different genotypes of the CYP17A1 single-nucleotide polymorphisms (SNPs). (A–C) Left hand 2D: 4D of rs17115149, rs1004467, and rs2486758 genotypes; (D–F) Right hand 2D: 4D of rs17115149, rs1004467, and rs2486758 genotypes. The black scatter points are individual 2D: 4D observations (including 400 men and 404 women). The box along with the upper and lower vertical lines represent the quartile range of 2D: 4D. Different colors of boxes represent different phenotypes. The horizontal line inside the box represents the mean value of the 2D: 4D. Remeasurement reliability of all digit lengths among 3 operators were acceptable for both hands in the intra-class correlation coefficient test.
