Geographic and Socioeconomic Variability in Commercially Negotiated Pricing for Hip and Knee Arthroplasty.
Article in JB & JS open access. 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
Background: Total hip and knee arthroplasty (THA/TKA) are among the most common and costly orthopedic procedures in the United States. While hospital-level pricing drivers are known, the influence of community socioeconomic and geographic factors remains unclear. This study aimed to evaluate both hospital-level and community-level predictors of THA/TKA pricing. Methods: A retrospective cross-sectional analysis used commercially negotiated THA/TKA inpatient hospital prices (Medicare Severity-diagnosis-related group 470) from 2,286 US hospitals encompassing 5,946 prices across 5 major commercial payers (Turquoise Health, March 2024). Prices are defined as claims costs reimbursed by payers, excluding surgeon, anesthesia, and outpatient fees. Hospital price data were linked to county-level socioeconomic, clinical need (e.g., arthritis prevalence), and hospital structural characteristics (e.g., bed count). Multivariate linear regression assessed associations between hospital/community factors and log-transformed prices. Results: Negotiated THA/TKA prices were significantly higher in rural than urban counties. Multivariate analysis found that higher prices were associated with larger hospital bed count (+5.20% per standard deviation [SD], p < 0.001), higher Case Mix Index (+5.34% per SD, p = 0.002), and counties with minority population populations (+3.19% per SD, p = 0.001) and uninsured rates (+2.91% per SD, p = 0.019). By contrast, higher arthritis prevalence (-3.13% per SD, p < 0.001) and Social Deprivation Index scores (-7.23% per SD, p < 0.001) were associated with lower prices, which suggests that high-need populations face lower hospital reimbursement or reflect price adjustments in response to local economic capacity. Conclusions: Commercially negotiated THA/TKA prices are influenced by both hospital structural factors and the demographics of the surrounding community. Higher prices in areas with larger minority populations and more uninsured residents may reflect systemic drivers of geographic and demographic disparities in healthcare pricing. Level of Evidence: Level III. See Instructions for Authors for a complete description of levels of evidence.
