Approximate 95% PIs are shown in parentheses.
*Predicted mean loss in percentage fat calculated from 3.90×fall in BMI−0.0339×fall in BMI2+0.818×time interval.
Standard error (SE) calculated from √{(0.990×(fall in BMI)2)+(0.000209×(fall in BMI2)2)+(0.199×(time interval)2)−(0.02836×fall in BMI×fall in BMI2−(0.07752×fall in BMI×time interval)+(0.000312×fall in BMI2×time interval)}.
