WPPSI (n = 11 dyslexia, 16 control)
	Full scale IQ	100 ± 17	104 ± 12	<0.48
	Verbal IQ	100 ± 15	101 ± 10	<0.70
	Performance IQ	101 ± 17	105 ± 18	<0.50

Values are shown as ratios or mean ± standard deviation. Significant group differences in proportions or means were tested using Fisher’s exact test or Student’s t-test, respectively.

WPPSI = Wechsler Preschool and Primary Scale of Intelligence.
