Conclusion
In conclusion, the screening and treatment intervention among asymptomatic pregnant women reduced the frequency of preterm or low birth weight infants compared to the standard-of-care among nulliparous women; however, the effect size among multiparous women and the entire sample was uncertain. As prematurity and low birth weight are leading causes of preventable death for children under five years, more research designed to detect differences in birth outcomes is needed for evaluating the effectiveness and cost-effectiveness of antenatalC. trachomatis and N. gonorrhoeae screening interventions.
