Figure 3 Average (A) and median (B and C) 2-year costs of treating knee OA for KA and non-KA patients. For the median plots, the light gray bars represent the 25th percentile (lower edge) and median (upper edge), while the dark gray bars represent the median (lower edge) and 75th percentile (upper edge).
