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

The literature has shown an inverse volume-outcome relationship for transcatheter aortic valve implantation (TAVI). However, little is known about emergency admissions in Germany. Using German national electronic health records, we identified all isolated balloon-expandable and self-expanding transfemoral TAVI in 2018. The focus was on those patients with emergency admission. 17,295 patients were treated with TAVI, including 1682 emergency cases. 49.2% of the emergency admissions were female, the mean age was 81.2 years and the logistic EuroSCORE was 23.3%. The percentage of emergency cases was higher in lower volume than in higher volume centers (p < 0.001): In detail, centers performing < 50 TAVI showed an emergency admission rate of ~ 15%, those with > 200 TAVI a rate of ~ 11%. After propensity score adjustment, analyzing the outcomes for an increase in volume per 10 emergency admissions, higher volume centers showed significantly better outcomes regarding in-hospital mortality (OR = 0.872, p = 0.043), major bleeding (OR = 0.772, p = 0.001), stroke (OR = 0.816, p = 0.044), mechanical ventilation > 48 h (OR = 0.749, p = 0.001), length of hospital stay (risk adjusted difference in days of hospitalization per 10 emergency admissions: - 1.01 days, p < 0.001), and reimbursement (risk adjusted difference in reimbursement per 10 emergency admissions: -€314.89, p < 0.001). Results were not significant for acute kidney injury (OR = 0.951, p = 0.104), postoperative delirium (OR = 0.975, p = 0.480), and permanent pacemaker implantation (OR = 1.010, p = 0.732). In conclusion, regarding transfemoral TAVI, the percentage of emergency cases was higher in lower volume centers in Germany. However, higher volume centers show significantly better outcomes for in-hospital mortality and complication rates as well as resource utilization parameters.
