The comparison of the clinical outcomes and costs between surgical aortic valve replacement and transcatheter aortic valve implantation based on the Japanese Diagnosis Procedure Combination database.
Article in Surgery today, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeWe evaluated the clinical outcomes and costs of surgical aortic valve replacement (SAVR) and transfemoral transcatheter aortic valve implantation (TAVI) for aortic stenosis using the Japanese Diagnosis Procedure Combination (DPC) database.
methodsUsing our extraction protocol, we retrospectively analyzed summary tables in the DPC database from 2016 to 2019, which were provided by the Ministry of Health, Labor and Welfare. A total of 27,278 patients were available (SAVR, n = 12,534; TAVI, n = 14,744).
resultsThe TAVI group was older than the SAVR group (SAVR vs. TAVI: 74.6 vs. 84.5 years; P < 0.01), with a lower in-hospital mortality (1.0 vs. 0.6%; P < 0.01) and a shorter hospital stay (26.9 vs. 20.3 days; P < 0.01). TAVI conferred more total medical service reimbursement points than SAVR (493,944 vs. 605,241 points; P < 0.01), especially materials points (147,830 vs. 434,609 points; P < 0.01). Total insurance claims for TAVI were approximately 1 million yen higher than those for SAVR. Regarding the details of costs, only the operation cost was higher, while other costs were lower with TAVI than with SAVR.
conclusionOur analysis revealed that both SAVR and TAVI showed acceptable clinical outcomes. TAVI was associated with higher total insurance claims than SAVR. If the material cost of TAVI operations can be reduced, greater cost-effectiveness can be expected.
