Table 3.

ICG fluorescence parameter values (mean ± std) based on the lesion region of interest median pixel value from each patient. Parameters include snapshot (a.u.), ingress slope (IS, a.u./s), time-to-peak (TTP, s), and max intensity (IMAX, a.u.). Statistical test results ($p$-values) reflect comparisons to the NSTI patient group.

IS (a.u./s)	4.2 ± 4.0	24.8 ± 15.2	0.04	32.8 ± 4.7	<0.01
TTP (s)	34.5 ± 35.6	19.5 ± 20.8	0.41	11.9 ± 3.5	0.24
