Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once a patient has been determined to meet all the eligibility criteria and has provided written informed consent, they will be allocated the next available sequential study number, and will be allocated the study drug bottle number corresponding to this. The bottles will contain either ibuprofen or placebo but the treatment allocaiton will not be listed on the bottle, nor will it be accessible to any of the clinical investiagtors.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation sequence generated by an independant statistician using permuted blocks of variable block size, with no stratification.
Masking / blinding
Blinded (masking used)
