As shown in Figure 2, when analyzing separately the data of subjects without fracture from those of patients with hip fracture, it is observed that in the former group (Figure 2 A), there is a statistically significant correlation between OPG and Frailty Score values (ANOVA r =0.420; p<0.001), while in the latter group (Figure 2 B) the two variables are not correlated with each other (r=0.092; p=NS). Here, TNFRSF11B is linked to hip fracture.
