How to read these marks →- Increases physical performance
moderate
“The analysis revealed that whey protein supplementation improved physical performance (SMD = 0.561; 95% CI: 0.256, 0.865; n = 33) (Table 4; Figure 3 and Supplemental Figure S13).”
- Effect
- 0.561 standardised mean difference, 95% CI 0.256 to 0.865
- Population
- Older adults aged over 60, healthy and sarcopenic or frail, in randomised trials of whey protein alone; all trials pooled, not a subgroup
What did not
- No detected effect on fat mass
moderate
“In addition, results showed that supplementation with whey had no significant effect on fat mass (MD = −0.033; 95% CI: −0.465, 0.398; n = 12) (Supplemental Table S11).”
- Effect
- −0.033 mean difference, 95% CI −0.465 to 0.398
- Population
- Older adults aged over 60, healthy and sarcopenic or frail, in randomised trials of whey protein alone; fat mass reported in 14 of the 30 included trials
