Values are mean ± standard deviation (median) or numbers (percentages) unless otherwise indicated.

For some cells, n < 82 for controls and n < 59 for cases.

ABC-6 = Activities-specific Balance Confidence-6 scale.

BBS = Berg Balance Scale score

^*p < 0.05 compared with controls.

^**p < 0.01 compared with controls.
