Table 2 Chi square test showing perforation rate among different groups
From: Crestal endoscopic approach for evaluating sinus membrane elevation technique
| Group | No perforation | Perforation | P value |
|---|---|---|---|
| No. (%) | No. (%) | ||
| Group (A) | 2 (50.00) | 2 (50.00) |
X2 = 4.80 P (chi) = 0.03 |
| Group (B) | 8 (100) | 0 |
