Potential leak-related prognostic factors and SEAL score predictors

Leak-related parameters
Nasogastric tube at diagnosis
Anastomotic reinforcement
C-reactive protein
SEAL score predictors
POD of diagnosis*
Level of care at diagnosis*
Diet at diagnosis*
Leucocyte count*
Resection type*
qSOFA score*
Haemodynamic failure*

^*Leak-related parameters identified as prognostic factors after adjusting for confounders were included as predictors of the Severity of oEsophageal Anastomotic leak (SEAL) score to determine leak severity. POD, postoperative day; qSOFA, quick Sequential Organ Failure Assessment.
