The PICOS criteria for defining the research question1
| Parameter | Description |
|---|---|
| Population | Adults, group mean age ≥19 y |
| Intervention | Groups consuming greater than the protein RDA (>0.85 g · kg−1 · d−1) |
| Comparison | Groups consuming the protein RDA (0.8 ± 0.05 g · kg−1 · d−1) |
| Outcome | Changes in lean or fat-free mass |
| Setting | Randomized controlled trials |
| Research question | What is the effect of consuming greater than the protein RDA compared with the RDA on changes in lean mass in adults? |
