Vitamin D deficiency, functional status, and balance in older adults with osteoarthritis

Figure 2 Comparison of velocity (cm/s) of individuals with osteoarthritis in relation to vitamin D classification (deficiency/insufficiency and normal). A: Antero-posterior velocity; B: Medio-lateral velocity. The boxplots represent the median with interquartile range. The error bars represent minimum and maximum values for each group. ^a Statistically different, Mann-Whitney test, P < 0.05. A/P: Anteroposterior; M/L: Mediolateral.
