  1. Pain scores are reported as Median (IQR: 25th-75th percentiles); IQR = inter quartile range, FPS-R = Faces Pain Scale-Revised, FLACC = Faces, Leg, Affect, Cry, Consolability scale, PGA = parental global assessment. Two- sided Wilcoxon Rank Sum Test was used to compare pain scores between groups. *P < 0.05 was considered statistically significant
