Parameter of interest	Correlation of two sets	∆ Mean ± SD	∆ Range	Absolute ∆ Mean ± SD	P-value *	95% CI	ICC	LoA (lower to upper)
MD	0.259	0.1 ± 3.4	-8.1 to 9.9	2.5 ± 2.2	0.905	-0.94 to 1.06	0.06	-6.56 to 6.76
PSD	0.071	-0.5 ± 2.5	-5 to 8.3	1.9 ± 1.6	0.169	-1.24 to 0.22	0.24	-5.4 to 4.4

^∆: Difference between SITA-SAP and Matrix-FDT, LoA: limit of agreement, MD: mean deviation, PSD: pattern standard deviation, SD: standard deviation, CI: confidence interval,
