Association Between Regional Social Vulnerability and Race-Based Differences in Total Knee Arthroplasty Use Among Medicare Beneficiaries.
Article in Arthroplasty today, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: There is inequity in total knee arthroplasty (TKA) use between racial groups. The social vulnerability index (SVI) may characterize mechanisms underlying disparity, which is essential for identifying targeted interventions. We examined the relationship of the overall SVI and its themes with TKA use rates for Black and White Medicare beneficiaries and the difference in TKA utilization between these groups. Methods: We used 2013-2017 Medicare data to calculate annual TKA use rates per 1000 beneficiaries in each hospital referral region (HRR). Multivariable mixed-effects linear regressions estimated the relationship between social vulnerability and TKA use. Results: The mean (standard deviation) TKA rates were 9.4 (1.7) and 5.9 (2.2) per 1000 White and Black beneficiaries, respectively. HRRs with highest social vulnerability (quartile 4) had lower TKA rates for White (estimate for quartile 4: -1.7, 95% confidence interval [CI]: -2.2 to -1.1, Conclusions: Worse overall SVI was related to lower TKA use rates for both White and Black Medicare beneficiaries. Areas with the highest minority status and language vulnerability had disproportionately lower TKA rates for Black compared to White beneficiaries. Our findings suggest regional mechanisms that health-care professionals and policymakers will need to address to ensure equitable TKA access.
