Multivariate analysis using clinical and imaging features to determine the likelihood of SARS-CoV-2 (n = 106)a
| OR | OR (95% CI) | P Value | |
|---|---|---|---|
| Infarct | 0.47 | 0.13–1.72 | .25 |
| Oxygen saturation | 1.00 | 0.97–1.02 | .78 |
| Presence of GGO | 11.65 | 4.14–32.78 | <.001b |
↵a With regard to total number of patients with confirmed SARS-CoV-2 (28/106), only the 3 most discriminant characteristics from the univariate analysis (P ≤ .05) were included. If all 6 variables P ≤ .10 or all 10 variables P ≤ .20 were included in the model, the only significant predictor of positive PCR result was the presence of GGO (P < .001), but these findings are at an increased risk of bias in the OR estimation.
↵b P value <.05.
