Yie 1996.

Methods	Randomised clinical trial, China
Participants	83 hospitalised adults with carcinoma of oesophagus and cardia, at nutritional risk due to gastro‐oesophageal surgery Male:Female = 59:24 Mean age = 55 years Exclusion criteria: Heart, lung, liver, kidney or endocrine diseases
Interventions	Experimental group: Group 2: Based on the conventional treatment, enteral nutrition (homemade homogenate liquid made of: rice, lean meat, egg, carrot, milk powder, sugar, etc.) was started from the 5th ˜ 6th day after the surgery. The treatment course was about 6 to 10 days (average 7 days). The average calorie supply was 3562 KJ. (n = 16) Control group: conventional fluid infusion through peripheral vein from the 1st day after surgery; the liquid volume was about 3000 ml; the calories were about 3562 KJ (n = 37)
Outcomes	Reduced weight/ideal body weight, BMI, morbidity and the times of stool after EN
Study dates	Not stated
Notes	We did not include group 1 as the experimental group received an elemental diet. We found no contact information for the authors.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not described
Allocation concealment (selection bias)	Unclear risk	Not described
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants and personnel were not blinded.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not described
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	The number of participants with incomplete data was not reported.
Selective reporting (reporting bias)	Unclear risk	No protocol could be obtained.
For‐profit bias	Unclear risk	It was unclear how the trial was funded.
Other bias	Low risk	The trial appeared to be free of other components that could put it at risk of bias.
