From: Increased risk for the development of postoperative severe hypoxemia in obese women with acute type a aortic dissection

  BMI
Normal: <  25 Overweight: 25 to 30 Obesity: >  30
Gender Female 17 10 2
Severe hypoxemia 5 (29.4) 9 (90.0) 2 (100.0)
Non-severe hypoxemia 12 (70.6) 1 (10.0) 0
Gender Male 28 42 13
Severe hypoxemia 1 (3.6) 15 (35.7) 9 (69.2)
Non-severe hypoxemia 27 (96.4) 27 (64.3) 4 (30.8)
  1. Values are n (%)
  2. BMI body mass index
  3. The chi-square test for trend is significant for the association between incidence of hypoxemia and increasing BMI categories and gender (p < 0.001)
