Fig. 1From: Olfactory impairment in patients with primary Sjogren’s syndrome and its correlation with organ involvement and immunological abnormalitiesHigher rates of anosmia and hyposmia in pSS patients than controls. Olfactory function of pSS patients and controls, stratified into anosmia (olfactory threshold scores of 1–3), hyposmia (olfactory threshold scores of 4–7), normosmia (olfactory threshold scores of 8–10), and sensitive olfaction (olfactory threshold scores > 10) individuals. A chi-square test was used (χ2 = 10.526, P < 0.01)Back to article page
