ALB and chronic kidney disease: By multivariate logistic regression, independent predictors of LTBI among patients with severe CKD or those undergoing dialysis included age (O.R. 1.03, 95% C.I. 1.01–1.04, per year increment), presence of dialysis (O.R. 2.47, 95% C.I. 1.02–5.95, vs. presence of severe CKD), serum albumin (OR: 2.59, 95% C.I. 1.63–4.11, per 1 g/dl increment), and presence of radiographic finding compatible with prior TB (O.R. 2.90, 95% C.I. 1.45–5.83) (Table 2).
