^aTotal SNAQ (Simplified Nutritional Appetite Questionnaire) score < 14 (low appetite)
^bPhysical activity scores were categorised into three categories (low, moderate or high activity)
^cTotal physical activity performed, in minutes, per week
^dPhysical function scores (SF-36) were categorised to reflect whether or not participants had ‘poor physical function’ (if their physical function score was in the sex-specific bottom fifth of the distribution)
*Missing data due to questionnaire non-completion
**One participant in the control group dropped out of the study due to hospitalisation
