Days in hospital (unstandardized) regressed on each infection category (rows) as dummy variables and covariates separately with linear regression.
Days in hospital (unstandardized) regressed on infection category dummy variables and covariates, simultaneously, with stepwise backward elimination of nonsignificant covariate effects.
HIV test results were available for a subset of Siaya inpatients only; the 2 dichotomous variables represent 3 potential categories: (1) tested and positive, (2) tested and negative, and (3) not tested.
