EE: Diurnal Variation (2014)
What is the effect of diurnal (time of day) variation on resting metabolic rate (RMR) in healthy and non-critically ill individuals?
Based on the limited evidence reviewed, diurnal variation has minimal effect on resting metabolic rate (RMR) in healthy adults. Additional research on larger, more heterogeneous samples is needed.
- 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.
