Table 1 Summary of infrared reflective (IR) marker motion characteristics for evaluation dataset

	Training period	Testing period	Absolute difference	p-value
R (mm)	7.2 ± 2.9 [2.9–15.5]	7.1 ± 3.0 [2.9–16.5]	1.2 ± 1.7 [0.0–10.4]	0.87
T (s)	4.2 ± 1.5 [2.5–8.2]	4.2 ± 1.4 [1.1–8.4]	0.6 ± 0.9 [0.0–5.7]	0.97
v₉₀ (mm/s)	7.3 ± 2.0 [4.0–13.5]	7.4 ± 2.2 [3.8–17.5]	0.8 ± 0.9 [0.0–5.0]	0.74

R, Peak-to-peak motion range; T, period; v₉₀, 90th percentile of respiratory velocity. Values are presented as means ± standard deviations (SD) [range, min–max]. P-values are the paired t-test results between training period and testing period
