Transcatheter Aortic Valve Replacement in Low-Population Density Areas: Assessing Healthcare Access for Older Adults With Severe Aortic Stenosis.
Article in Circulation. Cardiovascular quality and outcomes, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
backgroundRestricting transcatheter aortic valve replacement (TAVR) to centers based on volume thresholds alone can potentially create unintended disparities in healthcare access. We aimed to compare the influence of population density in state of Florida in regard to access to TAVR, TAVR utilization rates, and in-hospital mortality. METHODS AND
resultsFrom 2011 to 2016, we used data from the Agency for Health Care Administration to calculate travel time and distance for each TAVR patient by comparing their home address to their TAVR facility ZIP code. Travel time and distance, TAVR rates, and mortality were compared across categories of low to high population density (population per square miles of land). Of the 6531 patients included, the mean (SD) age was 82 (9) years, 43% were female and 91% were White. Patients residing in the lowest category (<50/square miles) were younger, more likely to be men, and less likely to be a racial minority. Those residing in the lowest category density faced a longer unadjusted driving distances and times to their TAVR center (mean extra distance [miles]=43.5 [95% CI, 35.6-51.4];
conclusionsOlder patients living in rural counties in Florida face (1) significantly longer travel distances and times for TAVR, (2) lower TAVR utilization rates, and (3) higher adjusted TAVR mortality. These findings suggest that there are trade-offs between access to TAVR, its rate of utilization, and procedural mortality, all of which are important considerations when defining institutional and operator requirements for TAVR across the country.
