Procedural Volume and Outcomes in Lower-Extremity Peripheral Vascular Interventions: Insights From the NCDR Peripheral Vascular Intervention Registry.
Article in Journal of the American Heart Association, 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
backgroundLower-extremity peripheral vascular interventions (PVIs) are increasingly used for treatment of peripheral artery disease. However, the relationship between hospital and operator PVI volume with in-hospital major adverse limb events (MALEs) and major adverse cardiovascular events (MACEs) is not well established.
methodsWe used the NCDR PVI (National Cardiovascular Data Registry) registry, including procedural data from April 1, 2014, to December 31, 2019, assessing in-hospital MALEs and MACEs during hospitalization for PVI. Annualized PVI volumes were categorized on the basis of operator or site volume. Generalized linear mixed models assessed volume-outcome relationships after adjustment of covariates.
resultsBetween 2014 and 2019, 55 785 PVI procedures were performed at 97 hospitals by 555 operators. Adjusted analysis showed no statistically significant association between hospital volume and MALEs (highest versus lowest volume: odds ratio, 0.91 [95% CI, 0.74-1.11];
conclusionsIn contemporary practice, a significant relationship was observed between operator volume and adjusted PVI outcomes. Highest-volume operators had lower rates of in-hospital MALEs and MACEs compared with lowest-volume operators.
