Abscess complications among 207 episodes of Klebsiella pneumoniae bloodstream infection by biomarker group in study of hypervirulent K. pneumoniae, Japan, 2022–2024. Stacked bars show mutually exclusive categories of liver abscess only, nonhepatic abscess only, and both liver and nonhepatic abscesses. Bar height represents the percentage of episodes with any abscess complication; numbers within colored bar segments indicate case counts. Case counts and percentages are provided below each bar.
