aPrimary aim: HRQL was the only outcome mentioned and / or HRQL was the first outcome mentioned in the main text. Secondary aim: HRQL was not the first outcome mentioned in the main text and / or the study referenced a previous study, based on the same data set, reporting on different outcomes

bNumber of patients assessed for HRQL at the first assessment point as reported in the study report

cAs explicitly stated in the study report

dYes if a study explicitly stated in the study report that HRQL was assessed at either 3, 6, 9,or 12 months. Studies that used timeframes to cover several months, for example 1-3 months were assessed as unclear

* Based on the additional HRQL outcome data provided

‡We imputed the standard deviation

§We transformed the timing of assessment

♯The study from Lagergren et al. evaluated the same patient group as Avery et al., and reported outcome data for 9 months follow-up

aStudies that evaluated more than one patient group were entered more than once (e.g. the study from de Boer evaluated two patients groups and thus was entered twice).

bLeft-sided approach included ‘‘left thoracotomy,’’ ‘‘thoracoabdominal’’, ‘‘thoracolaparotomy’’, and "transabdominal". Right two phase included ‘‘Ivor-Lewis’’, ‘‘transthoracic’’, and ‘‘two-phase

esophagectomy’.’ Three phase included ‘‘threephaseesophagectomy’’ and ‘‘McKeownesophagectomy". Minimally invasive approach included "minimally invasive surgery", "Minimally

invasiveesophagectomy", and " VATS". Any techniques not within these categories were classified as ‘‘other’’.
