Distribution of SI values at different ages, stratified for genotypes and sex.

<p>SI values and their 95% confidence intervals at different ages for homozygotes of both <i>NMU</i> rs6827359 and <i>ADRB2</i> rs1042713 risk alleles (CC+GG, dark grey) and homozygotes for non-risk alleles (TT+AA, light gray) in subgroups of boys (panel A, n = 620, carriers of CC+GG = 101) and girls (panel B, n = 572, carriers of CC+GG = 85). Graph was obtained using SAS software (PROC SGPLOT with LOESS statement, see text). Local regression method implies that statistical power decreases at extreme <i>x</i> values (larger confidence intervals).</p
