CR1 and dengue disease: Among dengue patients, we observed that CR1 levels were positively correlated with platelet counts (Spearman's rho = 0.23; P < 0.0001) and weakly correlated with white blood cells (Spearman's rho = 0.16; P = 0.01), while CR2 levels were positively correlated with platelet counts (Spearman's rho = 0.33; P < 0.0001) and inversely correlated with AST (Spearman's rho = − 0.23; P < 0.0001).
