Partial-regression coefficients of log-transformed equations predicting the reference means of spirometric parameters in the young-age male and female groups.

Ln: natural logarithm. M: male. F: female. H: height. BW: body weight. BFM: body fat mass. R2: coefficient of determination adjusted for degrees of freedom. ΔLLN  =  reference mean – LLN in Ln form. Only the coefficients with statistical significance are presented (at least p<0.04).
