Results: The matched sample consisted of 4578 patients (2291 in each group). NOACs were found to significantly reduce the risk of stroke/SE compared to warfarin (Hazard Ratio (HR): 0.373, 95% confidence interval (CI): 0.247 - 0.564, p<0.001); but, no significant difference was seen between NOACs and warfarin in terms of reducing the risk of MI (HR: 0.864, CI: 0.594 – 1.257, p=0.446). NOACs were found to significantly reduce the risk of ICH (HR: 0.500, CI: 0.300 – 0.834, p=0.008) and OB (HR: 0.608, CI: 0.424 – 0.870, p=0.007); but no difference was seen in the risk of MGB (HR: 0.862, CI: 0.640 – 1.160, p=0.326) between NOACs and warfarin. NOACs were also found to reduce the risk of all-cause mortality (HR: 0.783, CI:0.656 – 0.873, p=0.007). The composite of effectiveness and safety outcomes, and all-cause mortality was statistically significant proving superior overall effectiveness and safety of NOAC therapy to warfarin therapy in terms of risk reduction (HR:0.685, CI:0.587 – 0.801, p<0.001).
