Self-Reported Cognitive Impairments in Office-Based Treatment for Opioid Use Disorder with Buprenorphine or Extended-Release Naltrexone.

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: Opioid use disorder (OUD) can be associated with cognitive impairment. However, little is known about how patients with OUD self-perceive any cognitive impairments, particularly in attention, executive function, and memory. No studies have addressed this issue in patients with OUD and self-reported adherence to office-based medication-assisted treatment (MAT). Methods: This was an observational, multisite, cross-sectional survey study to evaluate self-reported cognitive function in adults with OUD, enrolled at 7 sites in the U.S., who had received ⩾3 months of office-based MAT. A cognitive self-report survey was administered to a clinical sample of adults with OUD (N = 255) adherent to buprenorphine (BUP; N = 139) or extended-release naltrexone (XR-NTX; N = 116). Impairments in attention, executive function, and memory were assessed with relevant items of the Executive Function Index (EFI) and Prospective Retrospective Memory Questionnaire (PRMQ). Factor analysis explored item factor structure; item scores were summed to generate scales, and association was estimated by linear regression. Results: Approximately one-third of participants reported head injury and nearly one-half reported psychiatric comorbidities, particularly anxiety and depression. Most participants reported difficulties in ⩾1 cognitive item: 80.8% (206/255) for EFI and 49.0% (125/255) for PMRQ. Factor analysis suggested 3 cognitive scales (attention, executive, memory). Differences between the XR-NTX and the BUP groups on memory, executive function, and attention either were not found or lost significance after adjustment for neurological history. seizure). All scales were associated with a range of demographic and clinical variables. Conclusions: Most adults receiving office-based MAT for OUD reported self-perceived cognitive impairment, but neurological comorbidities may also play a role in these perceptions.
