|---|---|---|---|
O vs. A | 0.42,[0.20-0.88],(0.019) | 0.43, [0.21-0.88],(0.02) | 1.02,[0.60-1.72],(0.93) |
O vs. B | 0.38,[0.16-0.89],(0.02) | 0.47,[0.21-1.06],(0.07) | 1.23,[0.66-2.29 ],(0.50) |
O vs. AB | 0.19,[0.07-0.51],(0.0005) | 0.33,[0.14-0.78],(0.009) | 1.69, [0.76-3.73 ],(0.19) |
O vs. (A,B & AB) | 0.35,[0.18-0.67],(0.0013) | 0.42,[0.22-0.78],(0.35) | 1.18,[0.76-1.84],(0.45) |
