Does the Clinically Significant Difference in Visual Analog Scale Pain Scores Vary with Gender, Age, or Cause of Pain?

Abstract

The minimum clinically significant difference in VAS pain scores was found to be 9 mm. Differences of less than this amount, even if statistically significant, are unlikely to be of clinical significance. No significant difference in minimum significant VAS scores was found between gender, age, and cause-of-pain groups.
