Mild autonomic dysfunction in primary Sjögren's syndrome: a controlled study

Table 3 Cardiovascular autonomic tests in pSS patients versus control individuals

	Mean (95% CI)
Cardiovascular autonomic test	pSS patients	Control individuals	P
Supine to standing: ΔSBP	+2 (-2 to +6)	9 (4 to 14)	0.031*
Supine to standing: 30/15 ratio	1.19 (1.14 to 1.24)	1.33 (1.27 to 1.40)	0.001*
Isometric grip: ΔMBP	22 (17 to 27)	27 (3 to 21)	0.24
Valsalva ratio	1.25 (1.18 to 1.33)	1.31 (1.25 to 1.37)	0.23
Breathing E/I ratio	1.17 (1.14 to 1.20)	1.18 (1.15 to 1.21)	0.66
Multivariate P value = 0.018

CI, confidence interval; ΔMBP, change in Finapres™ mean blood pressure (end of grip minus before grip); ΔSBP, change in brachial systolic blood pressure (5 minutes standing minus supine); pSS, primary Sjögren's syndrome.
