Is more better? A multilevel analysis of percutaneous coronary intervention hospital openings and closures on patient volumes.

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
backgroundIt is unknown how changes in the percutaneous coronary intervention (PCI) "built environment" have impacted PCI volumes at the community, hospital, and patient levels. This study sought to determine how PCI hospital openings and closures effect community- and hospital-level PCI volumes as well as the likelihood of receiving PCI at a low-volume hospital.
methodsWe conducted a retrospective cohort study of 3,966,025 Medicare Fee-For-Service patients in 37,451 zip codes and 2564 U.S. hospitals who underwent PCI from 2006 to 2017. We conducted community-, hospital-, and patient-level analyses using ordinary least squares regressions with fixed effects to determine changes in PCI volumes after PCI hospital openings or closures.
resultsBetween 2006 and 2017, a total of 17% and 7% of patients lived in communities that experienced PCI hospital openings and closures, respectively. Openings were associated with a 10% increase in community PCI volume, a 2% increase in the share of elective PCI, and a doubling in the likelihood of receiving PCI at a low-volume hospital. In communities with low baseline PCI capacity, openings were associated with a 12% increase in community PCI volume, and in high-capacity communities, an 8% increase. PCI closures were associated with a 9% decrease in community PCI volume in high-capacity communities but no measurable change in low-capacity communities.
conclusionsPCI service expansion is associated with increased PCI at low-volume hospitals and a greater number of elective procedures. Increased governmental oversight may be necessary to ensure that openings and closures of these specialized services yield the desired benefits.
