Influenza, influenza‐like symptoms and their association with cardiovascular risks: a systematic review and meta‐analysis of observational studies	2015-05-04		.txt	text/plain	4084	204	41	The quality of included studies was evaluated using a risk of bias assessment including: ascertainment of exposure to influenza, ascertainment of selected cardiovascular outcomes and adjustments for potential confounders. We stratified the main analysis based on the measures of ascertaining influenza (e.g. laboratory serology tests or based on clinical presentation suggesting influenza-like illness) and use of adjustments to account for potential confounders. Our findings suggest that exposure to influenzalike illnesses may be associated with increased risk of cardiovascular events, hence measures such as influenza vaccination should be supported in line with current recommendations, particularly among patients who are at risk of CVDs. The definition of influenza varied among studies in the current analysis since both serological tests and clinical assessments were used. We have observed that influenza-like illness defined by clinical features, which may be caused by both influenza and other viral infections such as those highlighted above are associated with an increased risk of MI.	./cache/cord-318753-ribybqfo.txt	./txt/cord-318753-ribybqfo.txt
