Figure 3. Temporal course of serum creatinine in patients with hantavirus infection, stratified according to (A) platelet count and (B) leukocyte count at initial evaluation. Platelet count, but not leukocyte count, is a significant predictor of subsequent renal failure (p = 0.004, Mann-Whitney). Box plots with median, interquartile range, minimum and maximum values are shown. n.s., not significant; WBC, leukocyte count.
