Real-world data on the effectiveness of TYRX and TauroPace for preventing CIED infections.

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
backgroundThe implantation of cardiac implantable electronic devices (CIEDs) carries a known risk of infection. Two devices (TYRX and TauroPace) have been proposed to reduce this risk.
methodsThe aim of our study was to compare the effectiveness of TauroPace and TYRX. Real-world comparative studies were included. Data analysis was based on reconstruction of individual patient data from Kaplan-Meier curves using an artificial intelligence algorithm. The endpoint was CIED infection or systemic infection. Statistical tests included heterogeneity assessment, superiority testing, and non-inferiority testing. The primary outcome measure was the hazard ratio (HR) with confidence interval (CI).
resultsOur literature search identified two real-world studies suitable for our analysis. Follow-up was 12 months for TauroPace (654 patients) and 60 months for TYRX (872 patients), with a total of 2,083 controls. There was no heterogeneity among controls. Compared to the pooled control group, patients treated with TYRX or TauroPace had fewer CIED infections (HR, 0.3892; 95% CI, 0.2042-0.7419; P=0.00414; HR, 0.3313; 95% CI, 0.1005-1.0925; P=0.06958, respectively). When testing for non-inferiority of TauroPace vs. TYRX, the comparison yielded a HR of 0.8494 (in favor of TYRX) with a 90% CI of 0.27-2.63; this CI of TauroPace did not meet the non-inferiority criterion set at HR>0.75 (i.e., relative difference ≤25%).
conclusionsBoth treatments had some important drawbacks. Regarding TYRX, more selective use in higher-risk patients should be advocated to improve its cost-effectiveness, but robust evidence is still lacking. Regarding TauroPace, our analysis testing for a non-inferiority margin of ≤25% did not meet this demonstration.
