Opioid Use Among Medicare Beneficiaries With Knee Osteoarthritis: Prevalence and Correlates of Chronic Use.
Article in Arthritis care & research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07638189 (Pilot Study Using Topical Cannabidiol), which is not on this map. Cited by 10 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
objectiveTo determine the prevalence of chronic and occasional opioid use and identify risk factors of opioid use among persons with knee osteoarthritis (OA).
methodsWe used the Medicare Current Beneficiary Survey to select a knee OA cohort. We obtained data on demographics characteristics, marital status, comorbidities, insurance, and prescription medication coverage from survey data and linked Medicare claims. We included all prescribed medication records classified as opioid under the First Databank therapeutic antiarthritics or analgesics categories. We stratified individuals with knee OA into 3 opioid use groups: 1) nonusers (0 prescriptions/year), 2) occasional users (1-5 prescriptions/year), and 3) chronic users (6+ prescriptions/year). We built multivariable logistic regression models using a generalized estimating equation to determine correlates of chronic opioid use.
resultsAmong 3,549 Medicare beneficiaries with knee OA and a mean ± SD age of 78 ± 7 years, 68% were female, 9% were chronic users, and 21% used opioids occasionally. Multivariable analysis showed that non-Hispanic ethnicity (odds ratio [OR] 4.8, 95% confidence interval [95% CI] 2.2-10.2), divorced status (vs. married; OR 2.3, 95% CI 1.5-3.5), Medicaid eligibility (OR 1.9, 95% CI 1.3-2.7), depression (OR 1.9, 95% CI 1.5-2.5), chronic obstructive pulmonary disease (OR 1.9, 95% CI 1.4-2.5), and inability to walk without assistive devices (vs. no difficulty walking; OR 2.4, 95% CI 1.5-3.7) were independently associated with chronic opioid use.
conclusionA total of 9% of persons with knee OA use opioids chronically. Efforts to find nonopioid regimens for treating knee OA pain should be tailored to patients at high risk for chronic use.
