change (SD) in score from T1 to T2.
squares average difference between yoga and WLC groups in change from T1 to T2 from linear mixed effects analysis.
UPDRS denotes Unified Parkinson’s Disease Rating Scale and motor function; MINI denotes Mini-BESTest; FGA denotes Functional Gait Assessment; FoG denotes freezing of gait Questionnaire.
