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
backgroundThe prescription of opioid medication is a frequent therapeutic approach in chronic noncancer pain, as is misuse of prescribed opioids. There is previous evidence for associations between personal variables such as impulsivity and opioid misuse. Psychological flexibility and inflexibility have also been associated with pain-related outcomes and opioid misuse. The aim of this cross-sectional study was to examine the combined role of a dispositional variable (impulsivity) along with psychological factors (Psychological Flexibility and Inflexibility) in pain outcomes and opioid misuse.
methodsThe sample comprised 155 people with chronic noncancer pain. A hypothetical model was tested using correlation and structural equation modelling analyses.
resultsThe results show significant associations between impulsivity and Psychological Flexibility, Psychological Inflexibility and opioid misuse. Psychological Flexibility and Inflexibility were related to pain intensity, interference and opioid misuse. Structural equation modelling showed significant associations between impulsivity, Psychological Inflexibility and pain interference, and opioid misuse. Associations between Psychological Flexibility and pain interference and opioid misuse were nonsignificant. These results support the hypothesis that impulsivity and Psychological Inflexibility are factors that contribute to pain interference and opioid misuse, but do not support the hypothesis that Psychological Flexibility reduces opioid misuse.
conclusionsIt is recommended to assess these psychological aspects prior to the prescription of opioid medication, and, if necessary, offering Acceptance and Commitment and Mindfulness Based Therapies could be desirable. SIGNIFICANCE: The results of this study provide further evidence of the role of trait impulsivity as a transdiagnostic antecedent variable in opioid misuse, both by a direct association and through psychological inflexibility. It can be drawn from these results that psychological transdiagnostic variables, rather than pain outcomes alone, would be key factors influencing opioid misuse. These findings underscore the need for comprehensive psychological assessments prior to the prescription of opioids.
