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
backgroundOptimized pathways for transcatheter aortic valve implantation (TAVI) have been reported over the past decade, but they considered specific devices and selected populations.
objectivesThe aim of this study was to assess the safety and efficacy of a comprehensive, minimalistic approach to TAVI utilizing all available devices in all-comers, real-world population.
methodsThis is a prospective, single-center, single-arm clinical study. The primary endpoint of the study was a composite of 30-day all-cause mortality, disabling stroke, major bleedings, major vascular complications, stage 3 acute kidney injury (AKI), and permanent pacemaker implantation (PPI). Outcomes were compared to those of an historical cohort of patients undergoing TAVI following a standard approach, by selecting pairs of patients selected through a 1:1 propensity score matching (PSM). A cost analysis of TAVI hospitalization was performed considering costs related to procedural complications and post-procedural length of stay (LoS).
resultsBetween January 2020 and December 2023, a total of 997 patients underwent TAVI following an optimized, minimalistic pathway. Device success was reported in 88.2% patients, with low procedural complications. The primary endpoint occurred in 21.1% of patients. After PSM, TAVI patients following the minimalistic pathway had higher device success (91.4% vs 84.2%, p = 0.004), and lower major vascular complications (4.5% vs. 10.3%, p = 0.004) compared to those following the standard approach. Median LoS was shorter (1.0 day vs. 2.0 days, p < 0.001) and the rate of next-day discharge was higher (46.7% vs. 19.0%, p < 0.001) in patients following the minimalistic pathway, with lower hospitalization costs (median € 2200 vs. 3150; p < 0.001). At 30-day, the primary endpoint was significantly lower in patients following the minimalistic pathway (17.2% vs 23.9%, p = 0.034).
conclusionsThe minimalistic TAVI care pathway was associated with favorable outcomes in an unselected, real-world population. The shorter post-procedural LoS of the minimalistic approach led to a significant cost-saving.
