Figure 4.

The ROC curves of hub miRNAs and core genes were plotted and correlations with these key genes and vital osteoporosis-associated factors were assessed. (a and b) The AUCs of ROC curves about hub miRNAs and core genes were calculated. (c–e) Correlation coefficients with these key genes and vital osteoporosis-associated factors including RUNX2 (c), CALCA (d), and BMP2 (e) were exhibited.
