Multivariate analysis of risk factors for coronary artery lesions
| Risk factor (cut-off point for categorical variable) | Exclusion of white blood cell count post-additional IVGG (n = 44) | Inclusion of white blood cell count post-additional IVGG (n = 39) | ||
|---|---|---|---|---|
| Odds ratio (95% CI) | p value | Odds ratio (95% CI) | p value | |
| CI, confidence interval; IVGG, intravenous gammaglobulin. | ||||
