One hundred and forty-nine diabeticpatients were followed for 17 years (a subset of data from Lee et al., 1988). Exercise Table 3.4 gives the survival time from baseline examination, survival status, and several potential prognosticfactors at baseline: age, body mass index (BMI), age at diagnosis of diabetes, smoking status, systolicblood pressure (SBP), diastolicblood pressure (DBP), electrocardiogram reading (ECG), and whether the patient had any coronary heart disease (CHD). Identify the important prognostic factors that are associated with survival.
