Inclusion Criteria: * They were systematic reviews based on randomized controlled trials (rcts). They were phase II rcts comparing chemotherapy with other systemic therapy agents or with no further treatment for recurrent, metastatic, or persistent cervical cancer. they reported at least one of these outcomes: complete or partial response rate, overall or progression-free survival rate, adverse effects, or healthrelated quality of life (rcts reporting on heterogeneous populations-for example, women at a range of disease stages-were included if results were given separately for patients with recurrent, metastatic, or persistent cervical cancer). Exclusion Criteria: * studies evaluating the role of radiotherapy administered with chemotherapy, or second- or subsequent-line therapy options.
