Factors	p^a	Cases
Factors	p^a	OR (95% CI)
Age (years)^b	< 0.001	1.048 (1.029, 1.068)
Male sex^b	< 0.001	6.240 (3.356, 11.601)
Socioeconomic status (D/E class^b)	< 0.001	3.347 (1.906, 5.879)
History of a previous contact with a case^b	< 0.001	3.859 (2.206, 6.752)
PCR^c	0.594	1.062 (0.594, 1.897)

a: Wald statistic; b: forward stepwise method adjusted to all variables in the model;c: polymerase chain reaction (PCR) was kept in the model to show it is not related to C and Co; OR: odds ratio; CI: confidence interval.
