Table 4.
Comparison of Programmed Cell Death 4 expression pattern of fibroblasts in normal oral mucosa, early oral submucous fibrosis, and advanced oral submucous fibrosis cases using Chi-square test
| Groups | PDCD4 pattern (intensity + percentage) | P | ||
|---|---|---|---|---|
|
| ||||
| Low/normal expression | Over expression | Total | ||
| Normal mucosa (1) | 0 (0) | 10 (100) | 10 (100) | 0.001* |
| Early OSMF (2) | 6 (40) | 9 (60) | 15 (100) | |
| Advanced OSMF (3) | 11 (73.3) | 4 (26.7) | 15 (100) | |
*P≤0.05, Chi-square test, PDCD4 expression scores: 0-2 low, 3-5 high. PDCD4: Programmed cell death 4, OSMF: Oral submucous fibrosis
