Summary of Computed Tomography-Derived Physiology among the Original Healthy, Original COVID-19, and Generated Healthy Images. CT density is displayed in Hounsfield units (HU). All measures are averages followed by their standard deviation. P values result from two-tailed paired t tests.

Images	Average CT density (HU)	Gas volume	Tissue mass
Original COVID-19	−652.5 ± 240.6**	2.45 ± 0.93**	1.27 ± 0.40**
Generated Healthy	−830.1 ± 152.3	3.01 ± 0.84	0.73 ± 0.29
Original Healthy	−816.9 ± 109.3	3.12 ± 0.83	0.75 ± 0.15

**P < 0.001 compared to Generated Healthy group.
