Distribution of frequencies for diagnosis of IE, 30-day and 1-year mortality. P = p value; PCR = polymerase chain reaction; PET/CT = F-18-FDG PET/CT; TEE = transesophageal echocardiography. Fischer’s exact test was applied, a p value < 0.05 was considered significant. Bold font highlights the respective diagnostic method and its p value, if significant.
