Treatment	No of participants*	No (%) with successful outcome†	Mean (SD) pain score‡
Advice leaflet	76	23 (30)	7.04 (4.21)
Diet only	122	42 (35)	6.96 (4.33)
Exercise only	82	38 (47)	5.70 (3.96)

*As randomised.

†≥30% reduction in pain score. Number with successful outcome includes those derived from multiple imputation.

‡Unadjusted for covariates, but allowing for multiple imputation.
