a The total number of observations was not 191 due to 0 oocytes retrieved in 2 patients; b The total number of observations was not 312 due to 0 oocytes retrieved in 5 patients; c Adjusted for age; d 114 cases in endometriosis group and 128 in control group; e 75 cases in endometriosis group and 179 cases in control group; f 19 cases in rASRM I/II group and 99 in the stage III/IV group, the significance is calculated between group rASRM I/II and III/IV.
