Table 1. Characteristics of included studies.
Figure 2. Forest plot to visualize effect sizes, represented as relative risk or hazard ratio, with corresponding 95% confidence intervals (95% CI) for studies included in the systematic review. Only studies examining colorectal cancer-specific mortality as an outcome are represented. Non-filled points are non-significant. It is important to note that due to high heterogeneity between studies, direct comparisons between individual studies should be interpreted with caution.

Figure 3. Forest plot to visualize effect sizes, represented as relative risk or hazard ratio, with corresponding 95% confidence intervals (95% CI) for studies included in the systematic review. Panel A) Only studies examining disease recurrence free survival as an outcome are represented. Panel B) Only studies examining disease free survival as an outcome are shown. Non-filled points are non-significant. It is important to note that due to high heterogeneity between studies, direct comparisons between individual studies should be interpreted with caution.
