Characteristics of the mean platelet volume, neutrophil to lymphocyte ratio, and C-reactive protein compared to the procalcitonin level in pneumonia patients

Figures & data

Figure 1. Associations between the procalcitonin level and mean platelet volume, mean platelet volume/platelet count ratio, neutrophil to lymphocyte ratio, and C-reactive protein in 102 pneumonia patients (The 52 patients were excluded for lower than 0.05 ng/ml procalcitonin level).

Figure 2. Associations between C-reactive protein level and mean platelet volume, mean platelet volume/platelet count ratio, and neutrophil to lymphocyte ratio in 154 pneumonia patients.
