HMIE: hybrid minimally invasive esophagectomy; CCI: comprehensive complication index. These scores are generated from http://www.assessurgery.com/about_cci-calculator/; continuous covariates are presented with median and minimum and maximum values; complications are graded according to the Clavien-Dindo score. The numbers represents the proportion of patients experiencing one or more complications of at least the grade indicated in the table.
