Prevalence of nicotine, alcohol, and cannabis use disorders among adults with chronic pain: Protocol for a systematic review and meta-analysis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Chronic pain is a significant public health problem associated with substantial medical expenditures, decreased quality of life, and physical and mental health comorbidities. Substance use is an important clinical consideration in pain, as substance use has been identified as both an antecedent and consequence of chronic pain. The majority of research on substance use and chronic pain has focused on opioid use, and although commonly used, alcohol, nicotine, and cannabis have received considerably less research attention. While there are empirical studies that examine the impact of non-opioid substance use in the context of chronic pain, the overall prevalence rates of nicotine, alcohol, and cannabis use disorders among adults with chronic pain have not been well-documented. Therefore, a systematic review and meta-analysis that characterizes the prevalence rates of non-opioid substance use disorders among adults with chronic pain is urgently needed. The current paper outlines the protocol for a systematic review and meta-analysis. It will include studies of adults with chronic pain that report on nicotine, alcohol, or cannabis use disorders, as well as problematic use (including co-use where available). The following databases will be searched: PubMed, Embase (Elsevier), Web of Science Core Collection, CINAHL (EBSCO), and PsycINFO (EBSCO). A team of trained research staff will conduct study screening and data extraction. Analyses will focus on pooled prevalence estimates of substance use disorders as primary outcomes and problematic use as secondary outcomes, with planned sub-group analyses and strategies to mitigate potential sources of bias. The results of this review will provide valuable clinical information on the scope of non-opioid substance use disorders, helping to guide future research as well as inform clinical and policy-level decision making.
