Stratifying the study population by CRP rs1205 genotype group showed that adolescent emotional problems were associated with the metabolic syndrome among CC homozygotes (OR = 1.83, 95% CI: 1.17, 1.86) with very similar differences in predicted probabilities for men (14.2%, 95% CI: 3.3, 25.1) and for women (12.6%, 95% CI: 2.6, 22.6), but not among T allele carriers (OR = 1.01, 95% CI: 0.66, 1.55; differences in predicted probabilities = 0.3%, 95% CI: −9.6, 10.1 for men, and = 0.02%, 95% CI: −7.6, 8.0 for women). The gene discussed is CRP; the disease is metabolic syndrome.
