Our paper entitled “Randomized clinical trial of arginine-supplemented enteral nutrition versus standard enteral nutrition in patients undergoing gastric cancer surgery” reported that arginine-supplemented enteral nutrition significantly improved long-term survival and restored immunity in malnourished gastric cancer. However, recently we checked our data again and found there was an obvious difference between experimental and control groups in the tumor status at the beginning of the trial. In addition, the sample size was not calculated, which might be not enough to reach a significant power. Thus, the trial might be biased and we, the authors, believe that the most responsible course of action is to retract our paper. We deeply regret this circumstance and apologize to the community.
