| Methods |
Randomised controlled trial.
Duration unclear, outcomes reported at different time points. Intervention given for 3‐5 weeks, survival reported to 1 year. |
| Participants |
Adults (n = 84, 50 men, 34 women, dietary advice and supplement group mean age 63.26 years, no advice group mean age 55.2 years) with cancer (various sites) undergoing radiotherapy. No information on nutritional status given. No information on attrition. |
| Interventions |
Dietary counselling and supplements versus (n = 42) no advice (n = 42). |
| Outcomes |
Survival*, energy intake*, macro and micronutrient intake. |
| Notes |
Data for survival given at 9 months for dietary advice and supplement group and at 11 months for no advice group. |

High risk |
No information on attrition. |
| Selective reporting (reporting bias) |
Unclear risk |
All outcomes reported. Mortality data obtained from the paper. Data on change in energy intake is expressed as mean (SD) at baseline and end of intervention therefore change scores were calculated and SDs imputed. No response received from author. |
| Other bias |
Unclear risk |
Baseline variables given, treatment group were older. |
