Risk of Venous Thromboembolism in Patients Nursed at Home or in Long-Term Care Residential Facilities
Table 2
Unadjusted analysis: results of the logistic model with log link to obtain relative risks for each risk factor. For each categorical variable the reference category is indicated by a relative risk of 1 and the corresponding risk of DVT is reported in brackets.
