An emulated target trial analysis based on Medicare data suggested non-inferiority of Dabigatran versus Rivaroxaban
Atrial fibrillation (AF) is an abnormal heart rhythm characterized by rapid and irregular heart chamber beatings. It affects three to six million people in the U.S.1, among whom 85% to 90% are eligible for oral anticoagulation therapies2,3. As established in the literature, it is of great interest to properly choose among non-vitamin K antagonist oral anticoagulants (NOACs). Rivaroxaban and Dabigatran were approved by the U.S. FDA in November 2011 and October 2010, respectively. They were the first two NOACs for preventing stroke for non-valvular AF patients and have been widely used since marketing.

Tobacco Product Use Among Adults - United States, 2017.
Abstract Cigarette smoking harms nearly every organ of the body and causes adverse health consequences, including heart disease, stroke, and multiple types of cancer (1). Although cigarette smoking among U.S. adults has declined considerably, tobacco products have evolved in recent years to include various combustible, noncombustible, and electronic products (1,2). To assess recent national estimates of tobacco product use among U.S. adults aged ≥18 years, CDC, the Food and Drug Administration (FDA), and the National Institutes of Health's National Cancer Institute analyzed data from the 2017 National Health Int...

Extension of Disease Risk Score-Based Confounding Adjustments for Multiple Outcomes Of Interest- An Empirical Evaluation.
Abstract Use of disease risk score (DRS)-based confounding adjustment when estimating treatment effects on multiple outcomes is not well studied. Using an empirical example comparing dabigatran versus warfarin on ischemic stroke and major bleeding risk in 12 sequential monitoring periods (90 days each) using the Truven Marketscan database, we compared two approaches for combining DRS for multiple outcomes: (1) 1:1 matching on prognostic propensity scores (PPS), created using DRS for bleeding and stroke as independent variables in a propensity score (PS) model; and (2) simultaneous 1:1 matching on DRS for bleeding ...
