Fig. 5. The relationships between the ADLs and 90% CIs of the calculated deviations. (A) Acceptable: Both the deviation and 90% CIs are within the ADL; (B) Acceptable: The deviation is with the ADL, and the 90% CIs overlap with the ADL despite in spite of either upper or lower limit being is out of the ADL; (C) Acceptable: The deviation is out of the ADL, but either upper or lower limit of 90% CIs overlaps with the ADL (red). Even if the upper or lower limit of 90% CIs is the same as the ADL, it is determined as acceptable (green); (D) Unacceptable: The deviation is out of the ADL, and there is no overlap between the ADL and the 90% CIs.
Abbreviations: ADL, allowable deviation from linearity; CI, confidence interval.
