But we found that whereas girls showed a trend of decreasing N3 duration with age ( r (30) = -.48, p = .008, 95 % CI [-.71, −.14]), boys did not ( r (25) = .11, p = .59, 95 % CI [-.30,.49]; see Figs. 2 A and 2 B), with a statistically significant difference between correlations ( z = -2.21, p = .014, 95 % CI of the mean difference [-1.03, −.06]).
