NRS‐3, Pain Intensity Score in the last three days; SQ, Sleep Evaluation Questionnaire; SF 36, Short Form 36 Health Survey; EQ5D VAS, EuroQol‐Health State Today; HADS, Hospital Anxiety and Depression Scale; PDQ, painDETECT questionnaire; PD‐Q clusters, subgroups of patients based on different painDETECT symptom profiles according to Förster et al. (2013) and Baron et al. (2012).

Patients who had available baseline data and who started with a titration of the treatment and could be followed up during the titration and maintenance period of the trial.
