Table 2:

(A) All non-imaging markers were assessed during clinical tests prior to MR imaging. %FEV1, DLCO/VA, RV/TLC, and FEV1/FVC were determined via PFT. (B) Non-imaging markers selected for the multivariate logistic regression were those values that had a p-value <0.25 from the univariate logistic regression.
