In obese adults, what is the prediction accuracy and maximum overestimation and understimation errors compared to measured resting metabolic rate when using the Owen et al formula?
The Owen, et al. equation predicted RMR within 10% of measured RMR in obese (BMI 30-40 kg/m2) individuals by 75% with the remaining 25% including 5% overestimations and 20% underestimations. In the same study, the Owen, et al. equation predicted RMR within 10% of measured RMR in 33% of severely obese (BMI >40 kg/m2) individuals with the remaining 67% including 7% overestimations and 60% underestimations. The individual error range was a maximum overestimate of 15% to a maximum underestimate of 37%.
- 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.
