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