Table 1. Associations between pulmonary tissue physiology outcome measures and lung tissue volume as determined by in vivo micro-CT.

PFT and micro-CT data for all 24 mice in this study were combined for non-linear correlation analyses of Total Respiratory Resistance (Rrs), Total Respiratory Compliance (Crs), and Inspiratory Capacity (IC). Spearman’s correlations for each set of parameters are listed for all data points.

Tissue Volume vs Rrs Tissue Volume vs Crs Tissue Volume vs IC
R2 (Non-Linear Fit) 0.4256 0.526 0.4382
Spearman’s Correlation (Rho) 0.4842 −0.6265 −0.5356
Spearman’s p value 0.0192 0.0014 0.0084
