Fig. 2From: Gait analysis following single-shot hyaluronic acid supplementation: a pilot randomized double-blinded controlled trialChanges in gait parameters from baseline to 4W post-injection (i.e., post-injection value minus baseline value) for the HA + mannitol group (HA + M), HA + sorbitol group (HA + S), and the saline group. Data are presented as medians (dot) and interquartile ranges (vertical lines). Significant changes between baseline and 4W are indicated with solid lines, whereas non-significant changes are indicated with dashed linesBack to article page
