The level of P-selectin in bacterial infection group was higher than in dengue and OFI groups, but it was not significantly different from healthy controls (36,672 pg/mL (25,932–49,662) (dengue patients) vs. 61,674 pg/mL (43,148–81,041) (bacterial infection) vs. 39,562 pg/mL (28,278–54,156) (OFI) vs. 39,900 pg/mL (33,270–71,412) (healthy controls)). This evidence concerns the gene SELP and dengue disease.
