Methods	Randomised clinical trial, China
Participants	79 hospitalised adult with AIDS, at nutritional risk due to surgery or mechanical ventilation Male:Female = 41:38 Mean age = 38.2 years Exclusion criteria: diabetes mellitus, hyperthyroidism, severe liver and kidney dysfunction, CD4 cell count > 200 /μl
Interventions	Experimental group: Enteral nutrition of non‐protein calorie 84 kJ/(kg/day), nitrogen 0.2 g/(kg/day). Participants received a guaranteed calorie intake every day of 83.6 ～ 146.3 kJ/(kg/day). The course of treatment was 5 ˜ 7 days. (n = 46) Control group: no intervention (n = 33) Co‐interventions: conventional treatment (glucose and saline as intravenous infusion)
Outcomes	T lymphocytes (CD3, CD4, and CD8), blood biochemical parameters.
Study dates	Not stated

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	The sequence generation was achieved using a random‐numbers table.
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 and the trial did not report on all‐cause mortality or serious adverse events.
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.
