  1. Data are mean ± SEM. Parameters were determined in the supine position at the end of a resting period of 30 minutes. P-values were determined in a two-tailed unpaired t-test between CC-genotypes (data column 1) and combined CT/TT-genotypes (data column 2). 95% CI: 95% confidence interval. (* P < 0.05).
