Design outcomes

Primary

Measure	Time frame
Main Objective: To evaluate the long term effectiveness of 40% salicylic acid plasters on corns when compared with 'usual' treatment which is scalpel debridement in terms of the proportion of unhealed or recurrent corns remaining over a 12-month period.;Secondary Objective: To evaluate the cost-effectiveness of corn plasters compared with scalpel corn removal, to compare patient centred outcomes in terms of pain, foot disability and quality of life and satisfaction. To explore podiatrists' views of the two treatments.;Primary end point(s): Presence at 3 months post randomisation of an unhealed or recurrent corn that requires further ongoing treatment.	—
