Fig. 4. IQ score differences between AD and AB deletion types in subjects with 22q11.2DS.

Fig. 4

IQ values were expressed as mean±SD. An independent-samples t-test was conducted to compare mean IQ scores in subjects carrying the AB deletion with those carrying the AD deletion. ***P < 0.001, **P < 0.01, *P< 0.05. Numbers in the shaded bars denote the samples size in each category. Full scale IQ, verbal IQ and performance IQ decreased by 0.3-0.5 SD among those in the AD group as compared with those in the AB group.
