Implementation of Intravascular Coronary Lithotripsy in the United States: Social Determinants of Health.
Article in JACC. Advances, 2025. 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
backgroundDisparities in health care access persist in cardiovascular interventions. Coronary lithotripsy, a novel treatment for calcified coronary lesions, shows variability in utilization by sociodemographic factors.
objectivesThis study examines the impact of sex, race, income, and hospital characteristics on lithotripsy use in the United States.
methodsUsing the 2021 Nationwide Inpatient Sample, patients undergoing percutaneous coronary intervention were identified. Lithotripsy was defined by the International Classification of Diseases-10th Revision codes. Multivariable logistic regression assessed the impact of sociodemographic factors, adjusting for comorbidities and hospital characteristics. Outcomes were compared using propensity score matching, with P < 0.05 considered significant.
resultsOf 261,260 percutaneous coronary intervention patients, 1,000 (0.38%) underwent lithotripsy. Adjusted analyses revealed that women were less likely to receive lithotripsy than men (adjusted OR [aOR]: 0.65; 95% CI: 0.53-0.79; P < 0.001). African American patients had lower odds of receiving lithotripsy than Whites (aOR: 0.66; 95% CI: 0.48-0.93; P = 0.016). Medicaid patients were less likely to receive lithotripsy (aOR: 0.20; 95% CI: 0.11-0.36; P < 0.001) compared to Medicare beneficiaries. Higher-income quartiles increased odds of receiving lithotripsy compared to lower quartiles (aOR: 1.38-1.6; P < 0.05). Regional disparities were noted, with lower use in the South (aOR: 0.66; 95% CI: 0.47-0.94; P = 0.022).
conclusionsDisparities in lithotripsy utilization persist, driven by sex, race, insurance status, income, and geographic region. These findings emphasize the need for targeted interventions to promote equitable access to advanced cardiovascular therapies. While some disparities may reflect differences in disease prevalence, persistent inequities in treatment allocation warrant further investigation.
