ALB and myalgic encephalomeyelitis/chronic fatigue syndrome: In the univariate logistic regression analysis, a higher CFS (OR 1.50, 95% CI 1.06 to 2.14, p=0.023), prior CABG (OR 3.18, 95% CI 1.15 to 8.77, p=0.026), lower serum haemoglobin concentration (OR 0.71, 95% CI 0.54 to 0.91, p=0.010) and lower serum albumin concentration (OR 0.91, 95% CI 0.85 to 0.98, p=0.014) were significantly associated with an increased risk of 1-year mortality after Em-TAVR (online supplemental table 4).
