Children with complex congenital heart disease and new meta‐analyses.

The new meta-analyses of the IQ data revealed IQ scores comparable to those published before, with estimated mean IQ scores: full-scale IQ 95.80 (95% CI 93.52-98.07), verbal IQ 96.16 (95% CI 92.33-99.99), and performance IQ 96.09 (95% CI 92.92-99.25). The age effect reported for verbal IQ ( I p i =0.08) was no longer significant, the age effect for performance IQ could no longer be reliably calculated. Our systematic review data suggest this may occur in children with 2V CCHD: their Bayley scores at early age were about 10 points below the mean, whereas IQ scores at older age were close to the mean (full-scale IQ 97).
