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 |
