Kandel 2014.

Methods	RCT.
Participants	Frail adults.
Interventions	Dietary intervention versus dietary intervention and Nordic walking training versus dietary counselling for 8 weeks.
Outcomes	Gait speed, handgrip strength, frailty score.
Notes	Full paper not published. Available as an abstract only. This seems to meet the inclusion criteria for comparison 3 of the review but needs full assessment once the final paper is available. Contact with the senior author failed to clarify questions about the intervention groups.
