Power values calculated for each haplogroup in different comparisons.

aThese haplogroups (excluding R0a) correspond to those tested in the logistic regression models.bPower percentages were calculated as reported in [40]. The number of cases (Nc) was assumed different in each comparison, while the number of haplogroups (NH) was always set at 16. The underlined power values refer to haplogroups H1, R0a and the other haplogroups that were statistically significant in the logistic models (see Table 4).cH here includes H*, H8 and H9 of Tables 2 and 3.dHV here includes HV* and HV0 of Tables 2 and 3.
