EE: Diurnal Variation (2014)

Assessment
What is the effect of diurnal (time of day) variation on resting metabolic rate (RMR) in healthy and non-critically ill individuals?
- Conclusion
  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: III
  - 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.
