Dose–response meta-analysis of studies for the association between fish consumption (linear increment by 50 g/day) and colorectal cancer risk, overall and stratified by tumor site and sex.
| N Studies | SRR (for an Increase by 50 g/day) | Lower 95% CI | Upper 95% CI | p-Value | I2 | p-Value for Non-Linearity | |
|---|---|---|---|---|---|---|---|
| Colorectal cancer | 7 | 0.96 | 0.92 | 0.99 | 0.021 | 0.0% | 0.071 |
| women | 5 | 0.95 | 0.90 | 1.01 | 0.078 | 0.0% | 0.880 |
| men | 6 | 0.97 | 0.92 | 1.02 | 0.188 | 0.0% | 0.280 |
| Colon cancer | 6 | 0.96 | 0.92 | 1.01 | 0.140 | 0.0% | 0.991 |
| Rectal cancer | 6 | 0.95 | 0.89 | 1.02 | 0.174 | 0.0% | 0.248 |
SRR: summary relative risk. CI: confidence intervals.
