We found that, in the early phase of septic shock, plasma IL-6 (obese 106, IQR 34 to 686; overweight 190, IQR 44 to 2,339; BMI of less than 25 kg/m2 235, IQR 44 to 1,793 pg/mL; P = 0.046) levels were significantly lower in obese and overweight patients than in those with a BMI of less than 25 kg/m2 (Figure 3). Here, IL6 is linked to Shock.
