When compared to placebo plus prophylaxis, the RR of flares ranged from 1.08 (95% confidence interval [CI] 0.87\u20131.33) for febuxostat 40 mg plus prophylaxis to RR 2.65 [95% CI 1.58\u20134.45] for febuxostat 80 mg plus lesinurad 400 mg plus prophylaxis. Compared to ULT alone, the RR of flares was lower for ULT plus rilonacept 160 mg (RR 0.35 [95% CI 0.25\u20130.50]), ULT plus rilonacept 80 mg (RR 0.43 [95% CI 0.31\u20130.60]) and ULT plus colchicine (RR 0.50\u00a0[95% CI 0.35\u20130.72]). There was limited evidence for other flare prophylaxis and on prophylaxis harms and optimal duration. Primarily because of missing outcome data and bias in the selection of reported results, 71.4% and 63.4% of studies were assessed as high risk of bias for flares and adverse events, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The RR of flares when introducing ULT varies depending on ULT drug and dosing strategies.
