Values are median, 95% CIs, and range for 6 measures of hair bundle structure in stiff and compliant bundle groups [height of kinocilium (Kino), height of tallest (TallSt) and shortest (ShortSt) stereocilia, height of kinocilium divided by height of tallest stereocilia (KS ratio), array length (Array), difference in height of tallest and shortest stereocilia divided by array length (Slope)]. Nonoverlapping CIs suggest significant differences between groups.
