*Two degrees of freedom.
†Four degrees of freedom.
‡In multilevel logistic regression model the residual variance at the nurse level is a function of the estimated model parameters and will therefore vary for each individual nurse unless the data (independent variables) for one or more nurses are the same.
HCSW, healthcare support worker; RN, registered nurses.
