IL6 and Cirrhosis: In patients with cirrhosis, younger age [estimate −0.01 (−0.03, −0.00), p = 0.0044], lower Child-Turcotte-Pugh class [estimate −0.23 (−0.45, −0.01) for class B + C, p = 0.0365], and lower IL-6 [estimate −0.10 (−0.18, −0.01), p = 0.0355] were independently associated with higher anti-Spike IgG response.
