Univariate regression analysis defined high lymphocytic count and NLR ratio as highly significant (p<0.001) predictors for the possibility of finding endometriotic lesions on laparoscopy, while high monocytic count and serum CA125 as significant (p=0.009) predictor for positive laparoscopy for EM and high SIRI and high grade on US imaging are weakly predictors for positive laparoscopy for EM (P=0.016 & 0.021, respectively) as shown in table 4. The gene discussed is MUC16; the disease is erythema multiforme.
