Fig. 1From: Dengue virus infection-enhancement activity in neutralizing antibodies of healthy adults before dengue season as determined by using FcγR-expressing cellsOverall analysis of neutralizing antibody titer in serum samples obtained from 100 healthy volunteer residents before (pre) and after (post) exposure to the dengue season in 2015 in Ha Noi. P-value determined by Fisher’s exact test. P value ≤0.05 = significant. Neutralizing antibody titers were determined on BHK cell lineBack to article page
