Table 1 Analysis of Variance (ANOVA) comparison of intelligence quotient (IQ) and birth weight.The mean (M) IQ score was 100 with a standard deviation (SD) of 15. ANOVA revealed significant differences (F [1.217]=41.49, P<0.001). Overall, birth weight explained only ~16% of the variance in IQ. The average IQ of children with very low birth weight (VLBW <1500 g) or extremely low birth weight (ELBW <1000 g) was 96.38, while the average IQ of children with normal birth weight (NBW ≥2500 g) was 12.98 points higher.
