Bias, mean difference between predicted and criterion body fat percentage; lower, lower limit (bias −1.96 SD); upper, upper limit (bias +1.96 SD); trend, correlation (expressed as Pearson’s r) between the difference and average. Subjective rating of SEE is from Lohman (39).
*
Significant correlation (P < 0.001).
**
Trend is significant (P < 0.01).
