1 · What the graph read from it

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.

2 · The registry

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

objectiveWe evaluated trends and outcomes of aortic valve-preserving surgery (AVPS) in Japan, particularly with regard to aortic regurgitation (AR), in comparison with data from 2014.

methodsWe conducted a nationwide survey across 244 hospitals in Japan, focusing on aortic valve and aortic root surgeries performed in 2019. The breakdown of procedures, including isolated aortic valvuloplasty (AVP) and valve-sparing root replacement (VSRR), in AR patients was examined, and compared with the results from 2014.

resultsIn 2019, the isolated AVP rate for AR was 5.5%, down from 7.5% in 2014. The VSRR rate among aortic root surgeries remained (33.1%). Within VSRR procedures, aortic valve reimplantation (reimplantation) accounted for 62.7% of cases, aortic root remodeling (remodeling) for 32.0%, and other root replacement techniques for 5.3%. AVPS was performed in 102 hospitals, with 10 institutions accounting for 42.2% of all cases. One-year reoperation rates for AVP, reimplantation, remodeling, and other root replacement were 8.0%, 1.8%, 6.0%, and 14.3%, respectively. Short-term (up to 4 years) aortic valve-related reoperation rates for AVP, reimplantation, and remodeling were 9.7%, 6.1%, and 9.5%, respectively. Use of a pericardial patch emerged as an independent risk factor for reoperation following AVPS (P = 0.022; odds ratio 3.382; 95% confidence interval 1.195-9.570).

conclusionsThe rate of AVP performed for AR in Japan decreased significantly from 2014 to 2019, while the rate of VSRR for root procedures remained stable. Use of a pericardial patch was identified as an independent risk factor for aortic valve-related reoperation following initial repair.
