Table 3

Results of one-sided Fisher’s test (OR < 1) of association between the various HLA alleles analyzed and the type of dengue infection (primary versus secondary infections).

HLA allele	Frequency (%)		Fisher’s test
	Primary	Secondary	OR (95% CI)	𝑃
B07	13.33	7.14	0.501 (0–0.99)	0.048
DR13	18.64	10.45	0.511 (0–0.91)	0.028

HLA: human leukocyte antigen; OR: odds ratio; CI: confidence interval; 𝑃: 𝑃 value.
