The results showed that disease duration, leukocytes, neutrophils, lymphocytes, mono-CRP, ferritin, and vitamin D deficiency, were independent risk factors for the diagnosis of BPPV (OR>1, p < 0.05), and monocyte count was an independent protective factor for the diagnosis of BPPV (OR<1, p < 0.05). This evidence concerns the gene CRP and vitamin D deficiency.
