were randomised to one of 2 groups; apple cider vinegar supplements (400 mg
tds) or placebo (dummy capsule). The study will be performed double blinded,
with participants and investigators unaware of study allocation. A follow up
clinic visit was made at 3 months, when weight was rerecorded, a food frequency
questionnaire re-administered, pain diary entries reviewed, and a pill count
performed to check compliance. All reports of gouty flare were validated
against rheumatology, emergency department and primary care records. <br></div>
