The impact of opioid use associated with curative-intent cancer surgery on safe opioid prescribing practice among veterans: An observational study.
Observational study in Cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundOpioid exposure during cancer therapy may increase long-term unsafe opioid prescribing. This study sought to determine the rates of coprescription of benzodiazepine and opioid medications and new persistent opioid use after surgical treatment of early-stage cancer.
methodsA retrospective cohort study was conducted among a US veteran population via the Veterans Affairs Corporate Data Warehouse database. Participants were opioid-naive persons aged ≥21 years with a new diagnosis of stage 0-III cancer between January 1, 2015, and December 31, 2016. Outcomes were days of coprescription of benzodiazepines and opioids in the 13 months posttreatment and new persistent opioid use. The exposure was total morphine milligram equivalents (MMEs) attributed to treatment and prescribed from 30 days before through 14 days after the index surgical procedure.
resultsAmong 9213 veterans, coprescription of benzodiazepines and opioids occurred in 366 patients (4.0%) and new persistent opioid use in 981 patients (10.6%). In a linear model adjusting for patient, clinical, and geographic factors, persons in the highest quartile compared to no opioid exposure had increased days with coprescription of benzodiazepines and opioids (mean difference, 1.0; 95% CI, 0.3-1.7). In a discrete time survival analysis, persons in the highest quartile of MME exposure compared to none had a greater risk of new persistent opioid use (hazard ratio, 1.6; 95% CI, 1.3-1.9).
conclusionsMore than one of 10 opioid-naive veterans undergoing curative-intent surgical treatment for cancer developed new persistent opioid use. Optimizing cancer treatment pain management strategies to mitigate long-term opioid-related health risks is crucial.
