Transition of Patients with Opioid Use Disorder from Buprenorphine to Extended-Release Naltrexone: A Randomized Clinical Trial Assessing Two Transition Regimens.
Trial report in The American journal on addictions, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectiveWhen patients seek to discontinue buprenorphine (BUP) treatment, monthly injectable extended-release naltrexone (XR-NTX) may help them avoid relapse. The efficacy of low ascending doses of oral NTX vs placebo for patients transitioning from BUP to XR-NTX is evaluated in this study.
methodsIn a phase 3, hybrid residential/outpatient study, clinically stable participants with opioid use disorder (N = 101), receiving BUP for more than or equal to 3 months and seeking antagonist treatment, were randomized (1:1) to 7 residential days of descending doses of BUP and low ascending doses of oral NTX (NTX/BUP, n = 50) or placebo (PBO-N/BUP, n = 51). Both groups received standing ancillary medications and psychoeducational counseling. Following negative naloxone challenge, participants received XR-NTX (day 8). The primary endpoint was the proportion of participants who received and tolerated XR-NTX.
resultsThere was no statistical difference between groups for participants receiving a first dose of XR-NTX: 68.6% (NTX/BUP) vs 76.0% (PBO-N/BUP; P = .407). The mean number of days with peak Clinical Opiate Withdrawal Scale (COWS) score less than or equal to 12 during the treatment period (days 1-7) was similar for NTX/BUP and PBO-N/BUP groups (5.8 vs 6.3; P = .511). Opioid withdrawal symptoms during XR-NTX induction and post-XR-NTX observation period (days 8-11) were mild and similar between groups (mean peak COWS score: NTX/BUP, 5.1 vs PBO-N/BUP, 5.4; P = .464). Adverse events were mostly mild/moderate. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Low ascending doses of oral NTX did not increase induction rates onto XR-NTX compared with placebo. The overall rate of successful induction across treatment groups supports a brief BUP taper with standing ancillary medications as a well-tolerated approach for patients seeking transition from BUP to XR-NTX.
