Histologic scoring was adapted from ISO 10993-6 standard.²⁴ Inflammatory cell outcomes and vascularity: 1 = 1–5/hpf; 2 = 5–10/hpf; 3 = heavy infiltrate; 4 = packed. Fibroblasts: 1 = rare-100/hpf; 2 = 100–1,000/hpf; 3 = heavy infiltrate; 4 = packed. Cellularity: 1 ≤ 25%; 2 = 26-50%; 3 = 51-75%; 4 = >75%. hpf = high powered field (40×).
