P values assess whether the correlation between PBFDXA and BMI is equal to the correlation between PBFDXA and the SF sum.
P < .001;
P < .05. In a random sample of 3500, a correlation of 0.055 would be statistically significant (H0: r = 0) at the 0.001 level.
Body fatness was categorized into 2 groups on the basis of the median PBFDXA for a child’s sex, age (year), and imputation number.
