Paton 2004.

Methods	Randomised controlled trial. Duration 24 weeks. Intervention for 12 weeks and follow‐up to 24 weeks.
Participants	Adults (n = 36, dietary advice and supplement group 8 men and 11 women mean (SD) age 39.5 years (14.3); dietary advice group 8 men and 9 women, mean (SD) age 38.4 years (19.3)) with tuberculosis and BMI <20. 10 participants lost to follow up, 4 in dietary advice and supplement group and 6 in dietary advice group.
Interventions	Dietary advice to achieve a calculated target intake and 2 ‐ 3x 200 ml supplement (n = 15) versus instruction to increase food intake (n = 13).
Outcomes	Weight*, BMI, body composition (DEXA), energy intake*, grip strength*, QoL, stand/sit test.
Notes	Additional data requested from author.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Sequence generated by a member of staff not otherwise involved in the study.
Allocation concealment (selection bias)	Low risk	Described as shuffling of sealed opaque envelopes.
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	10 participants lost to follow up, 4 in dietary advice and supplement group and 6 in dietary advice group.
Selective reporting (reporting bias)	Low risk	All specified outcomes reported but some in unusable format. Data on change in energy intake was presented in the text and not suitable for entry into meta‐analysis therefore obtained from author. Other data were extracted from the paper although 'n' for weight and grip strength were clarified with the authors.
Other bias	Low risk	Baseline variables given, groups similar at baseline.
