Thank you for your letter pointing out our mistake. When we were writing the manuscript, we missed the information of retraction. Other references [1,2,3,4,5,6] cited in our study can sufficiently support the results showing to the efficacy of preemptive analgesia with pregabalin in diverse surgery. Therefore, there is little or no effect drawing the conclusion of our study although a study by Reuben et al. was retracted [7].
