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
backgroundWhile approximately 17% of patients less than 80 years old require coronary access in the 7 years following their TAVR, the need for coronary access among older TAVR patients is unknown.
methodsWe examined the percentage of Medicare beneficiaries aged 80-90 years that require coronary access [percutaneous coronary intervention (PCI) or angiogram] in the 8 years following their TAVR using data from the Medicare 5% Standard Analytic File (2011-2021). The need for coronary access in older patients was estimated for all TAVRs, TAVR patients with and without a history of PCI, and TAVR patients with and without coronary artery disease (CAD) using time-to-event models adjusted for age, sex, race, region, ECI score, concomitant CABG, CAD, PCI, and current or recent smoker status. Multivariate log-gamma regressions were used to estimate the total cost of hospitalizations requiring coronary access post-TAVR.
resultsA total of 6845 patients met inclusion criteria. The incidence rates for undergoing PCI or angiogram at 1, 3, 5, and 8 years were 1.9%, 4.0%, 5.5%, and 6.3%, respectively. TAVR patients with PCI demonstrated higher rates of coronary intervention compared to those without PCI (10.2% vs. 6.2% at 8 years, respectively). Similarly, TAVR patients with a prior CAD diagnosis exhibited increased rates of coronary intervention compared to those without a prior CAD diagnosis (7.4% vs. 2.1% at 8 years, respectively). The mean adjusted cost of hospitalizations requiring coronary access was $30,170 [95% Confidence Interval: $27,865-$32,665].
conclusionsApproximately 6.8% of older TAVR patients require coronary access in the 8 years following their index procedure. The presence of a prior PCI or CAD diagnosis is associated with an increased requirement for subsequent coronary access.
