Assessment of Motor and Process Skills (AMPS) scores before and after the first period (parallel group analysis)

AMPS Variable	Waiting List first	Intervention first	Adjusted difference
	Baseline	After first period	Baseline	After first period	Difference (95% CI)	P value
Motor Score (Logits)	1.31 (0.48)	1.24 (0.40)	1.42 (0.88)	1.68 (0.45)	0.47 (-0.02; 0.96)	.059
	1.39 (0.62; 2.03)	1.33 (0.54; 1.61)	1.39 (0.37; 2.60)	1.67 (1.11; 2.32)
	n=6	n=6	n=7	n=6
Process Score (Logits)	0.81 (0.43)	0.91 (0.44)	0.77 (0.59)	1.38 (0.35)	0.47 (0.059; 0.89)	.0296
	0.64 (0.36; 1.38)	0.84 (0.43; 1.47)	0.60 (0.21; 1.87)	1.31 (0.87; 1.89)
	n=6	n=6	n=7	n=6

Variables are presented as Mean (SD) / Median (Min; Max). For comparing the change in outcome variables during the first period, analysis of covariance (ANCOVA) was used to adjust for the baseline values, with randomization group and baseline scores as independent variables.
