Multiple logistic regression for the effect of variables on PCR
| Variables | Coefficient (B) | Odds ratio (Exp B) | Confidence interval (CI) | P‐value |
|---|---|---|---|---|
| Sex (M/F) | 1.227 | 3.412 | (1.012, 11.507) | 0.048 |
| Moderate/severe | 1.393 | 4.027 | (1.196, 13.562) | 0.025 |
| Acute exacerbation/no exacerbation | 2.014 | 7.490 | (2.120, 26.460) | 0.002 |
Logistic regression equation: Y=(pos=1 vs. neg=0)=−4.084+1.227 × sex+1.393 × mod/sev+2.014 × exacerbation.
