Risk of upper gastrointestinal complications in a cohort of users of nimesulide and other nonsteroidal anti‐inflammatory drugs in Friuli Venezia Giulia, Italy

Abstract

IRs of UGIC in FVG decreased about 50% between 2001 and 2008. Nimesulide was in the low-medium range of RR. A complete ascertainment of UGIC cases in databases may require validation of nonspecific codes, secondary codes, and additional codes such as peritonitis and acute posthemorrhagic anemia.
