1
Comparison was made between groups using Yates’ continuity correction;
2
Comparison was made between groups using Fisher's exact probability test;
3
Comparison between groups utilized χ2 test; P > 0.05 was considered not statistically significant. P < 0.05 was considered statistically significant. COX-2: Cyclooxygensae-2.
