Faces Pain Scale-Revised (FPS-R) was used for the 6 to ≤ 12 years age group, (0 = no pain and 10 = very much pain).
Face, Legs, Activity, Cry, and Consolability (FLACC) behavior measurement was used for the 2 years to < 6 years and 0 years to < 2 years age groups, (0 = no pain and 10 = very much pain).
