PRIMARY outcome

Timeframe: April 2016 - December 2016

Population: Chronic neuropathic pain = DN4 ≥ 3 \& pain duration ≥ 3 months Chronic nociceptive pain = DN4 \< 3 \& pain duration ≥ 3 months No pain = no current pain or currently taking pain medication Note: Participants were included in the chronic neuropathic pain group if they satisfied the above criteria, regardless of the number of missing DN4 items, and excluded from the chronic nociceptive pain group if the number of missing DN4 items plus the their DN4 score totalled 3 or more.

Neuropathic pain will be identified according to the validated Douleur Neuropathique en Quatre Questions (DN4) questionnaire (English language)
