Fig. 2. Graph showing the sequential change of the visual analogue scale (VAS) after injection over time in each stage of ankle osteoarthritis (mean value and standard deviation at each time point shown; *p<0.05 in VAS between before injection and 3 months after injection, and ^†p<0.05 in VAS between before injection and 1 year after injection).
