Popis: Background: No consensus has been reached on prognostic value of serum concentration of β (beta) subunit of human chorionic gonadotropin (β-hCG) in treatment response to methotrexate in management of ectopic pregnancy. Therefore, the present study aimed to evaluate this subject through a systematic review and meta-analysis. Materials and Methods: An extensive literature search on online databases was performed. All studies performed on ectopic pregnancy patients treated by methotrexate from all age groups were included. After collecting data, random effect models were used to calculate the pooled standardized mean difference (SMD) of β-hCG level in treatment success and treatment failure groups. Finally, pooled performance screening characteristics of serum β-hCG level were assessed in different cut offs. Results: Finally, 51 articles were included in meta-analysis. Overall treatment success rate of methotrexate was 84% [95% confidence interval (CI): 84-85 percent]. A negative association was found between serum β-hCG level and the treatment response before intervention (SMD= -1.10, 95% CI: -1.39 to -0.88). In addition, pooled sensitivity, specificity, and prognostic odds ratio of β-hCG in the 2000 mIU/mL cut off were: 0.75 (0.65-0.82), 0.68 (0.58-0.82), and 6.0 (5.0-8.0), respectively. Conclusion: The present meta-analysis showed that serum β-hCG concentration before treatment could predict success of methotrexate in management of ectopic pregnancy.
