Effects of Maryland's All-Payer Model on elective joint replacement surgery.
Article in The American journal of managed care, 2025. 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
objectiveTo evaluate the Maryland All-Payer Model's impact on the rate of elective major joint replacement surgery. STUDY
designA retrospective cohort study of patients in Maryland undergoing elective major joint replacement between 2011 and 2018 was performed using a 20% fee-for-service Medicare sample in a difference-in-difference framework with patients undergoing hip fracture repair serving as controls.
methodsAmong Maryland residents, there were 7147 Medicare fee-for-service patients undergoing elective major joint replacement and 1008 Medicare fee-for-service beneficiaries undergoing hip fracture repair. We used patient-level generalized linear models with a negative binomial family function and a log link function to estimate the association of the All-Payer Model with the rate of elective major joint replacement surgery.
resultsUnder the All-Payer Model, the rate of elective major joint replacement surgery increased more than that of hip fracture repair (adjusted relative risk, 1.31; 95% CI, 1.15-1.51). Compared with hospitals without affiliates in adjacent states (Maryland-only hospitals), those with affiliates (Maryland hospitals with affiliates) saw rates of elective major joint replacement grow more slowly (adjusted relative risk, 0.87; 95% CI, 0.80-0.95) after the All-Payer Model. Furthermore, major joint replacement rates for Maryland residents at affiliated hospitals in adjacent states increased from 4.26 per 10,000 in the preintervention period to 5.23 per 10,000 in the postintervention period.
conclusionsUnder the All-Payer Model, population-based rates of elective major joint replacement surgery increased more rapidly than did rates of hip fracture repair. Although rates of major joint replacement at Maryland hospitals with affiliates grew more slowly than for Maryland-only hospitals, rates among Maryland residents increased at the affiliates in adjacent states.
