Intraobserver (bold, italic cells) and interobserver variability in the diagnosis of NRH after re-assessment of liver slides by seven pathologists. Six pathologists from six hospitals provided liver slides that had originally been diagnosed as NRH. Pathologist 1 corresponds with pathologist 1, etc. Pathologist 7 did not provide liver slides for this study.
