Thirty-six-month endometrioma recurrence-free survival analysis after conservative laparoscopic surgery according to the treatment modality adopted. (A) Oral contraception used for the entire follow-up period (n=102). (B) Oral contraception used discontinuously (n=129). (C) Expectant management (n=46). Pairwise log-rank test over strata: A versus B, P<0.001; A versus C, P<0.001; B versus C, P=− Vertical tick marks are censored observations.

Results of studies comparing conservative surgery for ovarian endometriomas with or without post-operative long-term oral contraceptive use. Horizontal lines indicate 95% CI; boxes show the study-specific weight; rhombi represent combined effect sizes; dashed line indicates the overall estimate. DerSimonian-Laird test for heterogeneity: chi-squared=6.07, P= OC=oral contraceptive; OR=odds ratio.
