Numeric scales to evaluate tissue inflammatory response in groups (Pereira-Lucena et al., 2014) [9].

Score	Cells Layers at the Margins of the Granulomas	Inflammatory Reaction in the Host Tissue	Inflammatory Response on the Mesh Surface	Tissue Maturation
1	1–4 layers	Non-dense, mature fibrous tissue	Fibroblast without macrophages or foreign body cells	Dense, mature interstitial tissue, similar to a normal connective or adipose tissue
2	5–9 layers	Immature fibrous tissue with fibroblasts and little collagen	Isolated foci or macrophages or foreign body cells	Interstitial tissue with blood vessels, fibroblasts, and a few macrophages
3	10–30 layers	Dense granular tissue with fibroblasts and many inflammatory cells	One layer of macrophages foreign body cells	Interstitial tissue with giant inflammatory cells but with permeating connective tissue
4	>30 layers	Mass of inflammatory cells, with disorganized connective tissue	Multiple layers of macrophages and foreign body cells	Mass of inflammatory cells without permeating connective tissue
