Table 3 Clinical characteristics of the SS and non-SS groups. Classification of the SS group by oral health-related quality of life (OHIP-14 score)

From: Deterioration in saliva quality in patients with Sjögren’s syndrome: impact of decrease in salivary epidermal growth factor on the severity of intraoral manifestations

  SS: severe (≥ 14) (n = 14) SS: mild (≤ 13) (n = 21) Non-SS (n = 23)
Age (years) 61.5 ± 10.4* 52.7 ± 14.0 56.1 ± 17.4
Disease duration (years) 7.2 ± 3.7 (n = 9) 4.9 ± 3.6 (n = 13)
Salivary flow rate (mL/10 min) 6.9 ± 4.2 9.3 ± 4.4 16.9 ± 5.9
