*1: Pleural surface is completely covered with mesothelium cells, 2: Fifty percent of pleural surface is covered with mesothelium cells, 3: Less than 50% of the pleural surface is covered with mesothelium cells, 4: Absence of mesothelium tissue.
**1: Mild: Almost no MIC, 2: Moderate: MIC count < 100, 3: Marked: MIC count > 100
***1: Mild: Almost no macrophages, 2: Moderate: Macrophage count < 100, 3: Marked: Macrophage count > 100.
