• Assessment
    In non-obese individuals, what is the prediction accuracy and maximum overestimation and understimation errors compared to measured resting metabolic rate when using the Owen et al formula?
    • Conclusion

      The Owen, et al. equation predicted RMR within 10% of measured RMR in 73% of non-obese adults in a high quality research methods design; the remaining 27% included 6% overestimation and 21% underestimation errors. The individual error range was an overestimate by 28% to an underestimate of 24%, indicating a large variation.

    • Grade: II
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
