Clinical Course, Prognosis, and Cause of Death in Primary Sjögren’s Syndrome

Table 6

Mortality risk in subgroups with significantly worse survival indicators, also taking into consideration the age recorded at the diagnosis.

Analysed variable	𝑃 value	Relative risk	CI 95%
Age at the diagnosis of pSS; (continuous variable)	<0.001	1.085*	1.049–1.121
Polyarthritis	0.048	1.898	1.006–3.581
Vasculitis	0.001	10.716	2.795–41.089
LPD	0.005	5.172	1.652–16.192
Cryoglobulinemia	0.038	2.331	1.048–5.185

∗With one year increase in age the risk for death is 1.085-fold higher.
