Bivariate associations between elevated CRP in young adulthood and measures of infectious exposures in infancy (excluding individuals with CRP > 10 mg l−1). Mean (s.d.) values are presented for continuous variables; percentages are presented for categorical variables. Two-sample t-tests (continuous variables) and Pearson χ2-tests (categorical variables) were used to evaluate differences between groups with CRP < 0.7 and CRP ≥ 7 mg l−1.
