Results
There was no significant difference between EMLA cream and LMX5 cream (difference 2.83; 95% confidence interval -11.25 to 16.92; P value 0.693). 

Compared with 65 minutes or less of coating time of the local anesthetic, the time of more than 65 minutes significantly reduced the VAS scores (difference -22.4, 95% confidence interval -39.5 to -5.34, P value 0.010).

Baseline Characteristics
The mean age was 36.7 years (range 25 to 29 years) and males were 33%. 

There were no statistically significant differences of background characteristics among the four groups. 
Participant flow
One participant was initially assigned to group 4, but when the cream was applied, the participant was mistaken regarding left and right. Due to the nature of this trial, the as-treated analysis was deemed to be more appropriate than the intention-to-treat analysis, and the participant was reassigned to group 1.
Adverse events
Regarding side effects, only one participant complained of mild itching at the application area of EMLA cream. Others did not have skin erythema or any serious side effects.
Outcome measures
There were no significant differences in primary and secondary outcomes between EMLA cream and LMX5 cream.
