Figure 2. Kaplan-Meier curve of the cumulative rate without local recurrence by surgical approach.

Reference as en-bloc resection and marginal resection, there was a HR (95% CI) of 11.25 (4.69, 26.97) in intracystic curettage, and 5.85 (2.45, 13.96) in resection partly with intracystic curettage, all P < 0.0001.
