PTPS NeP subjects with more severe pain experience, more interference with function.a

Notes: aScores on the BPI-SF Pain Severity were used to classify average pain severity. Three subjects did not respond to all required items needed to calculate a BPI-SF average pain severity score and thus were not included in any analysis by pain severity category. BPI-SF Pain Severity Index scored on a 0–10 scale. ***A statistically significant difference was observed across pain severity levels for BPI-SF Pain Interference Index: P < 0.0001.

Abbreviations: PTPS, post-traumatic/post-surgical; NeP, neuropathic pain; BPI-SF, Brief Pain Inventory-Short Form.
