Cardiac murmur	273 (26%)	253 (13%)
PR-interval, ms	170±32	162±24
25(OH)D, ng/mL^*	29.2±12.6	19.6±7.4
Betablockers	183 (18%)	113 (13%)

Values are shown as mean ± SD, or n (%).

Serum 25(OH)D was determined by a competitive protein-binding assay in the Original Cohort, and a radioimmunoassay in the Offspring Cohort. Due the use of different assays, serum concentrations cannot be directly compared between cohorts; standardized values were used in the regression analyses.
