Results of univariable analysis of risk factors for presence of antibodies against <i>Coxiella burnetii</i>.

#<p>Sera were screened for phase I and phase II IgG using a cut-off of 1∶32. Samples with both IgG phase I and II ≥1∶32 were considered to be positive, while solitary IgG phase II samples were scored positive if they had a single titre of ≥1∶512 (Focus Diagnostics, Cypress, CA).</p
