Supplementary Table 2 Percentages of CD8+ CD28- T cells in patients with ankylosing spondylitis, classified according to the grade of their movement restriction

From: Circulating cytotoxic CD8+ CD28- T cells in ankylosing spondylitis

  CD8+ CD28- T cells in patients (%)
  Minor Mean Major
Cervical rotation (sitting) 34.2 ± 17.3 45.0 ± 18.1 44.1 ± 16.3
Cervical rotation (lying) 36.9 ± 18.1 48.8 ± 15.3 44.7 ± 15.6
Tragus to wall 44.1 ± 17.2 41.8 ± 18.0 44.4 ± 16.5
Chin to jugulum 34.7 ± 18.2 43.5 ± 17.5 45.1 ± 16.3
Head to wall 39.8 ± 16.8 44.6 ± 18.6 40.5 ± 18.6
Chest expansion 35.5 ± 15.0 43.7 ± 18.9 43.2 ± 17.6
Thoracic Schober 39.3 ± 16.6 41.4 ± 18.7 42.8 ± 17.9
Modified Schober 41.0 ± 18.3 45.2 ± 15.3 43.7 ± 17.7
Lumbar side flexion 39.3 ± 16.3 45.5 ± 18.1 44.6 ± 16.9
Fingers to floor 36.8 ± 16.4 42.8 ± 18.8 43.9 ± 17.8
Intermalleolar distance 39.8 ± 17.4 44.5 ± 16.9 45.2 ± 17.2
  1. Patients were grouped in those with minor restrictions (head-to-wall distance <5, chin-to jugulum distance <3, cervical rotation in sitting position >70, thoracic Schober >32, chest expansion >6 and fingers-to-floor distance <20), those with mean restrictions, and those with major restrictions (head-to-wall distance >20, chin-to-jugulum distance >6, cervical rotation in sitting position <15, thoracic Schober <30.5, chest expansion <2 and fingers-to-floor distance >50). Correlations between the level of CD8+ CD28- T cells and the extent of movement restrictions were not significant (using Bonferroni adjustment after Pearson test).
