GPT and atrial fibrillation: Reduced levels of alanine transaminase (ALAT, OR: all = 0.755, SIC-positive = 0.564) and arterial pH (OR: all = 0.783, SIC-positive = 0.631) were associated with AF episodes in the overall sepsis and the SIC-positive cohorts, whilst reduced values of thrombocyte count (OR: SIC-negative = 0.659) increased the AF risk in the SIC-negative cohort.
