Population: Analysis population included all participants on pregabalin (Lyrica) at three months follow-up. For Baseline and Month 3 telephonic interview, "n" signifies those participants who were evaluable for this outcome. For Month 1 to Month 3, "n" signifies number of observations.

Sleep Interference was assessed on an 11-point Sleep Numeric Rating Scale (NRS-11) where a score of 0 indicated "pain did not interfere with sleep" and a score of 10 indicated "pain completely interfered with sleep". Here, "n" signifies "Number of participants" for Baseline and Month 3 telephone interview whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.

Timeframe: Baseline, Month 1, 2, 3

Population: Safety analysis set included those participants who received at least 1 dose of the drug under study. Here number of participants analyzed "N" signifies those participants who were evaluable for this measure. For Baseline, "n"=those participants who were evaluable for this outcome. For Month 1 to Month 3, "n"=number of observations.

Health-related Quality of Life was measured using Euro Quality of Life-5 dimensions (EQ-5D) scale. EQ-5D is a standardized generic instrument to assess health-related quality of life on 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression). The scale rates current participant's health state on a scale from 0 (worst imaginable health state) to 1 (best imaginable health state); higher scores indicate a better health state. Here, "n" signifies "Number of participants" for Baseline whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.

WPAI questionnaire assess work productivity and impairment. It is a patient-rated, six-item questionnaire regarding current employment, hours missed and actually worked, and degree to which a specified health problem affected work productivity and regular activities over the past seven days. Subscale scores include Percent work time missed due to pain (PWP), Percent overall work impairment (PWI), Percent work productivity impairment due to pain (PWPI), Percent overall activity impairment (PAI). Each subscale score is expressed as an impairment percentage (0-100) where higher numbers indicate greater impairment and less productivity. Here, "n" signifies "Number of participants" for Baseline whereas "n" signifies "number of observations" for Month 1, 2 and 3 because a participant could have had multiple visits during Month 1, 2 and 3 as this was a non-interventional study with no scheduled study visits, except Baseline visit and the Month 3 telephone interview.
