Regression analysis of the Bland–Altman differences between devices showed a weakly significant poor model fit for R5 ( R 2 = 0.06, p < 0.05) and for R20(19) ( R 2 = 0.07, p < 0.05).
Regression analysis of the Bland–Altman differences between devices showed a weakly significant poor model fit for R5 ( R 2 = 0.06, p < 0.05) and for R20(19) ( R 2 = 0.07, p < 0.05).
Regression analysis of IOS versus AOS values for R5 and R20(19) showed highly significant model fits along with narrow confidence intervals, R 2 and ICC values exceeding 0.7 and 0.9, respectively (Table 2 and Fig. 2 ).
