Table 4.

Comparisons of two independent groups at T1; values are expressed in raw and Z-scores; errors are codified in agreement with MT guidelines (1: request for immediate intervention; 2: warning request; 3: sufficient performance; 4: criterion completely reached).

Comparisons of two groups at T1 (Retest 1).
	Control group		Experimental group		Mann-Whitney test
	M	SD	M	SD	Z	p	r	CRB
Text reading MT Z-score	−2.16	0.95	−1.31	0.53	−2.51	0.012	0.49	0.58
Text reading errors performance	2.00	1.08	3.15	0.89	−2.58	0.010	0.51	0.57
Non-words reading syll/s Z-score	−1.46	0.70	−1.23	0.69	−0.95	0.342
Non-words reading errors Z-scores	0.75	1.47	0.20	0.71	−0.85	0.395

Comparisons are calculated on Mann-Whitney test: Z-value (Z), p-values (p) of probability, effect size (r and CRB) are reported.
