Mixed models using FVC and DLco as response variables, and NL at −200 HU and +200 HU as the explanatory variable. The regression coefficient estimates (β) and their standard error (SE) are reported on the link function scale (natural logarithm -Ln-). For immediate reading, coefficient estimates were exponentiated (Exp). Finally, the comparison was carried out in terms of log-likelihood (Log-lik).
