(a) SCI-NeP subjects with more severe pain had worse physical and mental health status (scores on the BPI pain severity were used to classify average pain severity. No significant differences were observed across pain severity levels). ^†Population norms (PCS=49.7 and MCS=49.5) indicated by thick black horizontal lines. (b) General health status significantly worse among SCI-NeP subjects with more severe pain (scores on the BPI pain severity were used to classify average pain severity. Mean EQ-5D health-state utilities measured on −0.11 to 1.00 scale. A significant difference was observed across pain severity levels for health-state utilities (P=0.0004). ^†Population norm (0.87) indicated by thick black horizontal line). (c) SCI-NeP subjects with more severe pain had greater pain interference with function (scores on the BPI pain severity were used to classify average pain severity. BPI pain interference index scored on a 0–10 scale. A significant difference was observed across pain severity levels for BPI pain interference index (P<0.0001). Note: All domains (general activity, mood, walking ability, normal work, relations with other people, sleep and enjoyment of life) were significantly different by pain severity (P<0.0033)). (d) SCI-NeP subjects with more severe pain had significantly worse sleep outcomes (scores on the BPI pain severity were used to classify average pain severity. MOS Sleep Problems Index scored on a 0–100 scale. A significant difference was observed across pain severity levels for the index score (P=0.0034).^†Population norm (25.8) indicated by thick black horizontal line).
