In the multivariable models for association with bacterial coinfection we found no significant association between biomarkers thresholds and bacterial coinfection, but with a positive trend for PCT ≥ 0.44 ng/mL in the early symptoms group (OR 14.97; 95% CI 0.96–234.03; p = 0.054)(Table 4 and Supplementary Table 11).
