Table 1. Grading Systems for Evaluation of Lipid Deposition in Intimae and Media Tunica and Evaluation of Density of Smooth Muscle Cells (SMCs) Nuclei.
| Grading Systems | Evaluation | Grade |
|---|---|---|
| Evaluation of lipid deposition in intimae and media | ||
| Less lipid existence in the artery | + | 1 |
| Moderate lipid existence in the artery | ++ | 2 |
| Existence of lipid in most part of artery | +++ | 3 |
| Existence of lipid in all part of artery | ++++ | 4 |
| Evaluation of density of SMCs nuclei | ||
| Mild density SMC nuclei in the artery | + | 1 |
| Moderate density SMC nuclei in the artery | ++ | 2 |
| Severe density SMC nuclei in most part of artery | +++ | 3 |
| Extreme density SMC nuclei in all part of artery | ++++ | 4 |
