Prize reinforcement contingency management for treating cocaine users: how low can we go, and with whom?
Trial report in Addiction (Abingdon, England), 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07208266 (Contingency Management as a Behavioral Intervention for Patients With Opioid Use Disorder), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
aimsThis study evaluated the efficacy of a low-cost, prize reinforcement contingency management (CM) intervention for reducing cocaine use.
settingCommunity-based treatment centers. PARTICIPANTS AND
designCocaine-abusing out-patients (n = 120) were assigned randomly to one of three 12-week conditions: standard treatment, standard treatment plus CM with an expected maximum of $80 of reinforcement or standard treatment plus CM with an expected maximum of $240 of reinforcement.
interventionIn the CM conditions, patients earned the opportunity to win prizes for submitting negative urine samples and completing goal-related activities. MEASUREMENTS: Drug use was measured at intake and throughout a 3-month treatment period.
findingsPatients in the $240 CM condition achieved more abstinence than patients in the standard condition. Patients who initiated treatment with positive urinalysis results were most responsive to the CM intervention, with the $240 CM condition engendering the best effects in this subgroup. In contrast, patients who initiated treatment with negative urinalysis results generally remained abstinent during treatment, regardless of treatment assignment. On average, patients in the two CM conditions earned $36 and $68 in prizes.
conclusionsThis study suggests that prize reinforcement CM may be suitable for community-based settings, and beneficial effects may be magnitude-dependent in more severe patients.
