The largest asthma research platform in the world is now live! Last week, QUANTIFY published the article “NORDSTAR – Paving the way for a new era in asthma research” in the ERJ in collaboration with Novartis and the Nordic Severe Asthma Network (NSAN). This milestone in the multiparty research collaboration known as the Nordic Research Dataset For Asthma Research (NORDSTAR) containing over 50 million patient years of population data from Denmark, Finland, Norway, and Sweden is the first step in an exciting new era of asthma research based on RWD.
