Comparison of the predicted correlation between SN-OP and FHR, FA respectively in different skeletal types. A Comparison of slopes for FHR to SN-OP. B Comparison of vertical intercept for FHR to SN-OP. C Comparison of slopes for FA to SN-OP. a: P < 0.05 vs. I-hypo group, b: P < 0.01 vs. II-hypo group, c: P < 0.0001 vs. I-nor group, d: P < 0.0001 vs. II-nor group, e: P < 0.0001 vs. I-hyper group, f: P < 0.0001 vs. II-hyper group. B Comparison of vertical intercept for FHR to SN-OP. a: P < 0.01 vs. II-hypo group, b: P < 0.01 vs. I-nor group, c: P < 0.0001 vs. II-nor group, d: P < 0.0001 vs. I-hyper group, e: P < 0.0001 vs. II-hyper group
