Performance of commercial dengue NS1 ELISA and molecular analysis of NS1 gene of dengue viruses obtained during surveillance in Indonesia

Table 3 ANOVA result based on logistic regression of the samples on various factors

Parameters	df	NS1^a		IgM^b
		χ²	p-value	χ²	p-value
City of origin	7	19.21	0.008 ^c	7.42	0.387
Serotype	4	6.60	0.159	9.78	0.044 ^d
Infection status	1	5.92	0.015 ^c	11.14	<0.001 ^d
Severity	2	2.53	0.282	4.29	0.117

df: degree of freedom.
χ²: Chi-square statistics, p-value < 0.05 is considered statistically significant (printed in bold).
^aLogistic regression model: NS1 ~ City + Serotype + Infection status + Severity.
^bLogistic regression model: IgM ~ City + Serotype + Infection status + Severity.
^cOmission of samples from cities with small samples size (Kendari and Medan) did not affect the statistical significant (p = 0.003 for city of origin and p = 0.034 for infection status).
^dOmission of samples from cities with small samples size (Kendari and Medan) did not affect the statistical significant (p = 0.034 for serotype and p < 0.001 for infection status).
