3.5 MBW outcomes before and after quality control
We determined whether performing quality control significantly influenced MBW results in our subset of measurements. We found no differences in LCI or FRC mean values or variability reported by the MBW operator compared with the reviewer before and after real-time quality control (Supplemental Table E2 and E3). Further, we assessed the impact of accepting D grade trials with LCI and FRC values within 10% of an acceptable trial on MBW outcomes and variability. We found no significant differences in LCI, FRC, or outcome variability (LCI/FRC coefficient of variation) between tests with and without accepting these D trials (Supplemental Table E4).
