Study details	Outcome measure	Outcome assessment	Results ERS vs. C
Chalder 2012 [29] Trial	MET minutes of physical activity a week - Meeting current exercise guidelines if MET ≥1000	4, 8, 12 months	Participants doing ≥1000 MET minutes of physical activity per week (%): 4 months - ERS = 52% - C = 43% 8 months - ERS = 63% - C = 49% 12 months - ERS = 58% - C = 40% Between group difference at 4 months Adjusted OR 1.58 (95%CI 0.94 to 2.66) P = 0.08 Between group difference using combined 4-, 8- and 12-month data Adjusted OR 2.27 (95%CI 1.32 to 3.89) P = 0.003
Murphy 2012 [30] Trial	7-D PAR	12 months	12 months adjusted between group difference in 7D-PAR score = OR 1.06 (95%CI 0.73 to 1.55) P>0.05
