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

Transcatheter aortic valve implantation (TAVI) in patients with severe aortic valve stenosis (AS) is becoming an established technique. However, data on long-term survival in Japan are limited and regional disparities remain. We aimed to evaluate long-term survival after TAVI using the Nara Kokuho Database (KDB). Patients who underwent TAVI between July 2014 and March 2023 were enrolled. The study outcomes were to evaluate survival rates after TAVI over 1-7 years and predict long-term prognostic factors using Kaplan-Meier analysis and Cox proportional hazards model. Of 446 consecutive patients, 284 were female participants (63.7%). The mean age was 84.1 ± 4.3 years. The overall survival rates were 95.1-54.4% over 1-7 years. Cox proportional hazards model analysis revealed that younger age (< 85 years, hazard ratio [HR], 0.38; 95% confidence interval [CI], 0.20-0.69; p = 0.002) and transfemoral approach (HR, 0.37; 95% CI 0.17-0.78; p = 0.009) were predictive factors. However, renal disease (HR, 2.02; 95% CI 1.08-3.77; p = 0.03), cerebrovascular disease (HR, 2.02; 95% CI 1.13-3.63; p = 0.02), and rheumatologic disease (HR, 2.71; 95% CI 1.19-6.18; p = 0.02) were poor long-term prognostic factors. This study measured the long-term survival after TAVI using Nara KDB data, identifying factors that might serve as predictive indicators.
