Response Letter to the Editor
First, I would like to thank Dr. Liu et al for his comments on the article “Early intake of solid food after Roux-en-Y gastric bypass and complications. A cohort study from the Scandinavian Obesity Surgery Registry” [1]. Propensity score matching is valuable tool for matching patients but as far as I am aware it has not been used for matching five groups which would be necessary to make the comparison done in the paper above.
