LS mean difference in change from baseline in ADPS at week 6. ADPS was derived from participants’ answer to question no. 5 of the BPI-DPN (“Please rate your pain due to your diabetes by indicating the one number that best describes your pain on the average,” using an 11-point numerical rating scale [0 = no pain to 10 = pain as bad as you can imagine]). Baseline value was defined as the average of the week 2 run-in period data. A minimum of 4 days (consecutive or nonconsecutive) of daily pain diary data from week 5 to week 6 was required for the calculation of mean weekly ADPS at week 6.
