Absolute and percentage change in left atrium to aortic ratio (LA:Ao), N-terminal pro B-type natriuretic peptide (NTproBNP) concentration and left atrial long axis measurement (LA long) compared between cats that went on to experience an event and those that did not at the first re-examination

Owing to missing data for at least one visit: values for absolute and percentage change in the LA:Ao and LA long were only available for 10 cats in the event group; and values for absolute and percentage change in NTproBNP concentrations were only available for 10 cats in the event group and 29 cats in the group that did not experience events
