For these vegan men, how long they'd been vegan, their age, muscle mass, or activity level didn't affect whether their bodies were losing protein on this diet.
Scientific Claim
Nitrogen balance in minimally active male vegans consuming 0.8 g/kg/d protein for 5 days showed no significant correlation with age, years of vegan diet adherence, fat-free mass, BMI, physical activity, or other measured variables.
Original Statement
“There were no significant correlations between nitrogen balance and age, years vegan, fat-free mass, BMI, physical activity, or other descriptive variable (p ≥ 0.100; Spearman rank correlation).”

Can only show association/correlation
Assessment Explanation
The study used Spearman rank correlation, which is appropriate for assessing associations in observational data. The claim correctly states no significant correlation.
