Table 1.
The MR results by 5 methods.
| Exposure | Outcome | Method | SNP (n) | OR | OR 95% CI | P value | |
|---|---|---|---|---|---|---|---|
| MCH | CRC | MR-Egger | 205 | 1.054 | 0.955 | 1.163 | .295 |
| MCH | CRC | Weighted median | 205 | 1.061 | 0.987 | 1.140 | .104 |
| MCH | CRC | IVW | 205 | 1.074 | 1.015 | 1.138 | .013 |
| MCH | CRC | Simple mode | 205 | 1.018 | 0.876 | 1.184 | .809 |
| MCH | CRC | Weighted mode | 205 | 1.064 | 0.996 | 1.136 | .063 |
CRC = colorectal cancer, IVW = inverse variance weighted, lci95 = lower 95% confidence interval, MCH = mean corpuscular hemoglobin, MR = Mendelian randomization, OR = odds ratio, SNP = single nucleotide polymorphisms, uci95 = upper 95% confidence interval.
