Optimizing retention strategies for opioid use disorder pharmacotherapy: The retention phase of the CTN-0100 trial (RDD).
Article in Contemporary clinical trials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04464980 (NIDA-CTN-0100), which is not on this map. Cited by 3 papers.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
INTRODUCTION AND
backgroundThe three medications approved to address OUD are effective in decreasing opioid use and morbidity and mortality; however, their utility is limited by high rates of dropout from treatment. The CTN-0100 trial will develop an evidence base for strategies to improve retention on buprenorphine and extended-release naltrexone. RESEARCH DESIGN AND
methodsThe National Drug Abuse Treatment Clinical Trials Network (CTN) study CTN-0100, "Optimizing Retention, Duration and Discontinuation Strategies for Opioid Use Disorder Pharmacotherapy" (RDD), is a multicenter, randomized, non-blinded trial enrolling more than a thousand patients from 18 community-based substance use disorder treatment programs. Participants are adult volunteers seeking to initiate medication treatment for OUD (MOUD). Individuals choose between buprenorphine or extended-release injectable naltrexone. The trial randomizes participants choosing buprenorphine, in a 3 × 2 factorial design, to a medication condition (standard-dose sublingual buprenorphine, high-dose sublingual buprenorphine, or extended-release injectable buprenorphine) and to a behavioral condition (Medical Management or Medical Management plus a digital therapeutic (smartphone) app). Individuals choosing extended-release naltrexone are randomized only to a behavioral condition. Participants receive study medication for 74 weeks and are then followed for a further 24 weeks. The primary outcome is successful retention on MOUD at 26 weeks (six months), with 50- and 74-week retention among the secondary outcomes. DISCUSSION/
conclusionDropout from treatment is a major barrier to the effectiveness of MOUD. The CTN-0100 study will determine whether strategies such as high dose sublingual or extended-release buprenorphine, or an app-based behavioral intervention improve retention on MOUD.
