Table 1 Comparsion of the groups A, B and C

From: Wireless capsule endoscopy for the detection of small bowel diseases in HIV-1-infected patients

Group n (m/f) Age (year) CD4 cell count (/μl) Number of pathological findings Pathological findings proximal of the ligament of Treitz Pathological findings distal of the ligament of Treitz
A (HIV-positive) 19 (16/3) 46 ± 10 (31-61) 78 ± 60 (1-187) 30 13 (68%) 17 (89%)
B (HIV-positive) 19 (15/4) 44 ± 10 (30-63) 118 ± 52 (10-196) 22 17 (89%) 5 (26%)
C (HIV-negative) 11 (6/5) 37 ± 4 (31-44) - 13 8 (73%) 5 (45%)
  1. Group A: HIV positive, CD4 cell count < 200/μl, gastrointestinal symptoms present. Group B: HIV positive, CD4 < 200/μl, without gastrointestinal symptoms. Group C: healthy volunteers.
  2. Fisher's exact test:
  3. Pathological findings proximal of the ligament of Treitz:
  4. Group A vs Group B; p = 0.232
  5. Group A vs Croup C; p = 1.000
  6. Group B vs Group C; p = 0.327
  7. Pathological findings distal of the ligament of Treitz:
  8. Group A vs Group B; p = 0.001
  9. Group A vs Croup C; p = 0.028
  10. Group B vs Group C; p = 0.425
