  2. bMultiply imputed values. Multiple imputations carried out to account for up to 12% of the EQ-5D-5 L utility scores (2 or 1% of baseline and 19 or 1% of 3-month EQ-5D-5 L scores)
  3. cThese scores have been adjusted for baseline differences
  4. dThese PG-SGA scores were reverse scored so that a positive score reflects an improvement in nutrition status
  5. eTrial participants with complete information on baseline and 3-month outcomes
