METHODS AND RESULTS Of two real-world registries, the Watchman registry Lichtenfels, Germany, and the Amplatzer registry Bern-Zurich, Switzerland, 303 and 333 consecutive patients, respectively, were included. After a 11 propensity score matching, 266 vs. 266 patients were compared by use of the predefined primary efficacy endpoint of stroke, systemic embolism and cardiovascular/unexplained death, the primary safety endpoint of major peri-procedural complications and major bleeding events at follow-up, and the combined hazard endpoint, a composite of all above-mentioned hazards. Mean age was 75.3 ± 7.8 (Watchman) vs. 75.1 ± 9.9 (Amplatzer) years, CHA2DS2-VASc score 4.5 ± 1.7 vs. 4.5 ± 1.5, and HAS-BLED score 3.2 ± 1.0 vs. 3.2 ± 1.0. At a mean follow-up of 2.4 ± 1.3 vs. 2.5 ± 1.5 years and 1.322 patient-years, the primary endpoints of efficacy [40/646, 6.2% [Watchman] vs. 43/676, 6.4% [Amplatzer]; hazard ratio (HR), 1.02; 95% confidence interval (CI), 0.66-1.58; P = 0.92] and safety (33/646, 5.1% vs. 30/676, 4.4%; HR, 0.57; 95% CI, 0.29-1.11; P = 0.10), as well as the combined hazard endpoint (69/646, 10.7% vs. 66/676, 9.8%; HR, 0.80; 95% CI, 0.55-1.12; P = 0.26) were similar for both groups. CONCLUSION This study suggests comparable efficacy and safety of the Watchman and Amplatzer devices. Published on behalf of the European Society of Cardiology.

A salient step in many studies is to identify editing sites that statistically associate with treatment (e.g. case vs. control) or covary with biological factors such as age. However, RNA-seq has technical features that incumbent test
