*** Prevalence of depression and anxiety significantly greater in patients with cancer compared with a non-cancer control group (P < 0.001).
Note: The No. of studies per row is based on the independent group of cancer vs. control group. However, some studies included multiple control groups (e.g., disease and normal control). Thus, the total No. of studies per subgroup of control group is higher than the total number of the included studies in our meta-analysis.
