Advanced biomarkers for prognostic evaluation of pneumonia severity in pediatric intensive care: focus on novel inflammatory and hematological ratios

Mortality was significantly associated with infectious agent type, respiratory support type, LOS, lactate, and L/A ratio. CRP, CRP/MPV, and L/A ratio differed significantly between clinical severity groups. CRP/MPV may be useful in assessing mortality, clinical severity, and respiratory support type. However, L/A ratio was found to be a more valuable predictor of mortality than lactate alone.
