Figure 2. Plots of Geometric Centers in subjects with asthma vs. healthy subjects.

Figure 2

A. The ventral deviation of calculated geometric center of ventilation defects (GCVdef) from the geometric center of the lungs (GCLung). Both healthy subjects and subjects with asthma demonstrated a vertical dependence in Vdefs. However healthy subjects have a significantly (P = .028) lower ventral deviation compared to that of subjects with asthma. B. The horizontal (x-axis) deviation of calculated geometric center of ventilation defects (GCVdef) from the geometric center of the lungs (GCLung). (p>0.05).
