1 · What the graph read from it

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.

2 · The registry

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

objectivesThe prevalence of analgesic opioid (AO) misuse among patients with cancer-related chronic pain remains poorly understood, and no screening tool has been validated for this population. The Prescription Opioid Misuse Index (POMI), an eight-item self-administered questionnaire, was developed for chronic non-cancer pain. This study aimed to evaluate the psychometric properties of the POMI in a population of patients with chronic cancer-related pain.

methodsThis prospective observational psychometric study was conducted in two oncology day hospitals at the Clermont-Ferrand University Hospital. Eligible patients had active cancer, chronic pain lasting ≥ 3 months and were receiving daily opioid therapy. The POMI questionnaire was completed at inclusion (TEST) and 2 weeks later (RETEST). Psychometric properties were assessed following standard guidelines, including internal consistency, test-retest reliability and external validity using DSM-5 criteria for opioid use disorder as the reference standard.

resultsA total of 138 patients were included (58% men), with a mean age of 64 ± 10 years. Internal consistency of the POMI was low (Kuder-Richardson coefficient: 0.22). Test-retest reliability, assessed in 68 patients, showed moderate agreement (Lin's concordance: 0.43 [0.24-0.63]). Correlation between POMI scores and DSM-5 criteria was modest (Spearman's ρ = 0.25). According to the POMI, 11.6% of patients demonstrated opioid misuse versus 17.4% with DSM-5-defined use disorder.

conclusionsThe POMI lacks sufficient psychometric validity for use in oncology populations. Future tools should be specifically designed to address the clinical complexity and unique context of chronic cancer-related pain and opioid use.
