Analysis was limited to 451 (86%) of the 525 patients discharged improved, and 65 (78%) of the 83 patients who died for whom information on each of the variables entered into the final iteration of the multiple logistic regression analysis was available.

Variables significant (P<0.05) in the bivariate analysis but excluded from the multiple logistic regression analysis because information was available for a limited number of the 516 patients were blood glucose, available for 127 (25%) patients, and serum protein, available in 163 (32%) patients.
