Scoring details of histopathology analysis in this study.

Observed Tissue Change		Scoring
	0	1 (Mild)	2 (Moderate)	3 (Severe)
Inflammatory cell infiltrates	Not present	Infiltration by ≤ 10 mononuclear cells within a 20x field.	Infiltration of 11–50 mononuclear cells within a 20x field.	Infiltration of ≥ 51 mononuclear cells within a 20x field.
Cellular necrosis	Not present	Rare pyknosis and/or karyorrhexis of cells affecting ≤ 5% of the entire tissue.	Pyknosis and/or karyorrhexis of cells affecting 6–50% of the entire tissue.	Widespread pyknosis and/or karyorrhexis affecting ≥ 51% of the entire tissue.
Bacteria	Not present	Bacteria are present within ≤ two inflammatory cells within a 40x field.	Bacteria are present within 3–5 inflammatory cells and/or in a single extracellular aggregates within a 40x field.	Bacteria are present within more 5 inflammatory cells and within multiple extracellular aggregates within a 40x field.
