From: Role of NS1 antibodies in the pathogenesis of acute secondary dengue infection
DENV1 NS1 antibody responses to NS1 peptides in the febrile phase. a–h DENV1 NS1-specific IgG antibody responses to 61 DENV1 NS1 overlapping peptides in patients with DF (n = 10) and DHF (n = 10) were measured by ELISA on day 4 of illness. Differences in mean values between antibody responses to overlapping peptides in patients with DF and DHF were compared using the Mann–Whitney U test (two tailed). NS1 antibody levels in patients with DHF are indicated in red, and in those with DF in blue. Error bars indicate mean and standard deviation (SD). *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
