Kaplan‐Meier survival curves plotting the estimated percentage of dogs in each group in the per‐protocol population that have not yet experienced an event (defined as having reached the primary endpoint, undergone euthanasia or died for a noncardiac reason, had chronic medication initiated (Table 1 or Table 2), had a congestive heart failure endpoint that was not verified by the endpoint committee, the owner became noncompliant with study procedures, or the dog was withdrawn from the study by the owner or investigator), against time. There were 178 dogs in the pimobendan group and 176 dogs in the placebo group at the outset. CI, confidence interval.
