Figure 4 Overall cannulation rates. A: Cannulation rates of the two groups are shown in Forest plot. The overall cannulation rate was found to be 90% in pre-cut sphincterotomy group and 86.3% in persistent attempts group. The pooled analysis did not show any significant difference between the two groups with an OR 1.98 (95%CI: 0.70-5.65); B: The overall cannulation rates after excluding studies where direct pre-cut was performed. The results were unchanged. EPC: Early pre cut; PA: Persistent attempts.
