Number of data and p-value summary of overall treatment time (OTT) with and without Exactrac (ET), and the modulation factor (MU/Gy) for the 3 fractionations schemes used. Data is for treatments utilizing HD-MLC

		Median (IQR)	Number of fraction or plan	P-value
OTT (min) per fraction	With ET	23 (20–31)	165	≤10−23
	Without ET	12 (11–13)	55
Modulation factor (MU/Gy) per plan	Plan A: 1 × 18 Gy	339 (304–393)	145	A vs. B = 0.051
	Plan B: 3 × 9 Gy	320 (290–352)	25	A vs. C = 0.085
	Plan C: 1 × 13 Gy	367 (338–422)	12	B vs. C = 0.002
