  • a CSF-1R, colony stimulating factor-1 receptor.

  • b The percentage of cases in each group (high CSF-1R expression, low CSF-1R expression, and total patients) that were associated with a particular clinicopathological variable is shown in parenthesis.

  • c Scored on a scale of 0–3, with 0, no staining; 1, weak staining; 2, moderate staining; 3, strong staining.
