Rogers 1992.

Methods	Randomised controlled trial. Duration 4 months.
Participants	Adults (n = 28, mean age 62 years (SE 2.0 years)) with COPD and weight <90% of IBW and FEV1/FVC <0.6. 1 withdrawal in the no advice group.
Interventions	Nutritional counselling to achieve a balanced meal plan plus supplements as needed (n = 15) versus no dietary advice (n = 12). Advice provided during 4‐week inpatient phase and then at each outpatient visit.
Outcomes	Weight*, TSF*, MUAC*, grip strength*, respiratory function*, QoL.
Notes	Additional data and information awaited from authors.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Described as randomised, method not stated.
Allocation concealment (selection bias)	Unclear risk	Method not stated.
Blinding (performance bias and detection bias) Clinical outcomes	Unclear risk	Not stated.
Blinding (performance bias and detection bias) Functional outcomes	Unclear risk	Not stated.
Blinding (performance bias and detection bias) Nutritional outcomes	Unclear risk	Not stated.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	1 withdrawal in the no advice group. Reason not given.
Selective reporting (reporting bias)	Low risk	All specified outcomes reported but not in a format for entry into meta‐analysis. Change in weight, TSF, MAMC and handgrip strength are reported as mean (SD) at the start and end of intervention with a P value. No data obtained from authors therefore mean change (SD) derived using data in the paper.
Other bias	Low risk	Baseline variables given, groups similar at baseline.
