ALB and decubitus ulcer: At univariate (Table 3, showing only the factors significatively correlated to pressure ulcer) and logistic regression (Table 4) analysis, after adjusting for confounding factors, pressure ulcers were inversely associated with both MAC (Model I and III) and MAMC (Model II) (with MAC p = 0.04, beta = −0.89 Model I; with MACM p < 0.050; beta = −1.29 Model II; with MAC p = 0.02; beta = −0.98 Model III) as well as with both haemoglobin (p = 0.04, beta −1,1; Model I and Model II) and albumin (p = 0.04, beta −7.91 model III; Table 4).
