Fig. 3From: The maximal gait speed is a simple and useful prognostic indicator for functional recovery after total hip arthroplastyKaplan–Meier curves for functional recovery according to tertiles of maximal gait speed. Notes: The fast, middle, and slow maximal gait speed tertiles were ≥ 1.41, 1.05–1.41, and ≤ 1.05 m/s, respectivelyBack to article page
