Table 3: Six independent risk factors are included in the model: gender, age, heart failure history, chronic kidney disease, hyperlipidemia, and dyspnea. As for age, patients are divided into three groups according to their age, and the group in column 1 (age < 35) is used as the reference index in the model.
