<li>Data are expressed as mean &plusmn; SD (95% confidence interval). Note that for e&acute; velocity in subjects aged 16 to 20 years, values overlap with those for subjects aged 21 to 40 years. This is because e&acute; increases progressively with age in children and adolescents. Therefore, the e&acute; velocity is higher in a normal 20-year-old than in a normal 16-year-old, which results in a somewhat lower average e&acute; value when subjects aged 16 to 20 years are considered.</li>
