Regression Analysis Results for MRI Agreement with MRS

Intercept (%)
(95% CI)		 Slope
(95% CI)		 Regression Bias (%)
(95% CI)		 R2
(95% CI)
MRI-M 0.63
(0.36, 0.90)		 0.998
(0.977, 1.017)		 0.60
(0.41, 0.79)		 0.982
(0.976, 0.986)
MRI-C −0.07
(−0.37, 0.24)		 0.975
(0.950, 0.998)		 0.49
(0.23, 0.79)		 0.979
(0.970, 0.984)
p-value 0.0127 0.035 0.553 0.050

Note. p-values are the bootstrap-based p-values for comparing the regression metrics between MRI-M and MRI-C methods. After Bonferroni correction, only p-values of 0.0125 or less are considered to be significant at family-wise 0.05 level. Thus, the difference between intercepts is borderline significant, but there are no other significant differences.
