Efficacy of Web-Based Interventions on Depression and Anxiety in Cancer Caregivers: A Systematic Review and Meta-Analysis.

Web-based interventions might be effective in reducing depression and anxiety among informal caregivers of patients with cancer. Nevertheless, several studies with an overall high risk of bias were included. As a result of the limited number and heterogeneity of the studies included in the subgroup analysis, deriving definitive conclusions on the most effective intervention components was challenging. Therefore, further studies incorporating high-quality research are warranted.
