Table 2.

Simple linear regression models of SI-based indices with logarithmic values of 13C-MBT.

B (95% CI) p-value r
Log(13C-MBT) RE 0.507 (0.398–0.615) <0.001 0.665
SIpre 0.001 (−0.001–0.002) 0.213 0.120
SIpost 0.002 (0.001–0.002) <0.001 0.554

RE: relative enhancement as a function of SI-based indices. SI: mean signal intensity of the liver. 13C-MBT: 13C-labeled methacetin metabolism liver function breath test. r: correlation coefficient. B: linear regression coefficient. CI: confidence interval.
