- According to the Bland-Altman plot, the P value showed if there is agreement by using the t test. If this test showed no significant different (P > 0.05), a regression analysis was performed to see is if there is agreement, written in brackets; a Agreement according to the Bland-Altman plot
- Paired t-test: * P < 0.05, ** P < 0.01; ß Wilcoxon sign ranks test:* P < 0.05, ** P < 0.01 for the non-parametric parameter; SD, standard deviation; T12-L1, Thoracolumbar level
