Individual RSA (top) and Valsalva Ratio (bottom) scores for patients and controls at baseline and follow-up. Note Data points have been color-coded within each group and according to subject. Circular data points reflect scores or measurements falling within normal age- and gender-related ranges. Whereas triangular and square data points reflect scores or measurements > 50 % and < 50 %, respectively, of the lower normal age- and gender-related limits. Black vertical bars and corresponding values represent group means for each time point
