Calculated anchor-based clinically important differences. Italicized numbers indicate values that should be rounded according to resolution sensitivity. Clinically important difference (CID), 95% confidence interval (95% CI), not significant (ns), coefficient of variation (CV), more-affected/less-affected (MA/LA).
