Bias = RMR measured by Quark RMR-REE predicted by equations. Percent of bias = ((RMR measured by Quark RMR-REE predicted by equations) × 100)/REE predicted by equations. Accurate estimation = percentage of all subjects whose REE was within 90% to 110% of measured RMR by Quark RMR. Underestimation = percentage of all subjects whose REE was less than 90% of measured RMR by Quark RMR. Overestimation = percentage of all subjects whose REE was more than 110% of measured RMR by Quark RMR. r = Pearson’s correlation coefficient between RMR measured by Quark RMR and REE predicted by equations. significant difference vs the measured RMR (Quark RMR) (P ≤ 0.05).
