Figure 1. Proportion of children free of (a) their primary anxiety disorder and (b) all anxiety disorders at follow-up by 5HTTLPR genotype.
Note. 1(i). There were significant associations at follow-up between both “primary anxiety response” and “all anxiety response” respectively, using either a genotypic (χ22 = 8.61, p = .01; χ22 = 6.60, p = .04) or recessive (χ21 = 7.03, p = <.008; χ21 = 5.88, p = .02) model. 1(ii) Children with the SS genotype showed significantly greater reduction in symptom severity from pre-treatment to follow-up (β = −.15, p < .01). At post-treatment the difference was not significant (β = −.03, p = .55).
