Using a pragmatically adapted, low-cost contingency management intervention to promote heroin abstinence in individuals undergoing treatment for heroin use disorder in UK drug services (PRAISE): a cluster randomised trial

RCT (n=552) found contingency management intervention (behavioural intervention involving modest financial incentives alongside opioid agonist treatment) was superior to treatment as usual for heroine abstinence at weeks 9-12 (OR=2.1; 95% CI 1.1 to 3.9; p=0.030).
