Table 3 A synergistic impact of BMI and gamma gap on mortality rate with different adjustment models.

From: A synergistic impact of body mass index and gamma gap on heart failure and mortality rate among older patients with coronary artery disease: a prospective study with 10-year follow-up

Mortality rate

Hazard ratio (95% confidence interval), P value

 

High BMI, low gamma gap (n = 286)

Low BMI, low gamma gap (n = 387)

High BMI, high gamma gap (n = 128)

Low BMI, high gamma gap (n = 186)

Model 1

Reference

1.25 (1.04–1.51), P = 0.019

1.78 (1.40–2.27), P <0.001

2.30 (1.85–2.85), P <0.001

Model 2

Reference

1.19 (0.98–1.43), P = 0.075

1.68 (1.32–2.14), P <0.001

2.20 (1.78–2.74), P <0.001

Model 3

Reference

1.09 (0.90–1.33), P = 0.380

1.51 (1.19–1.93), P = 0.001

1.65 (1.32–2.07), P <0.001

  1. Model 1: unadjusted; model 2: adjusted for age and sex; model 3: adjusted for age, gender, heart rate, diastolic blood pressure, hemoglobin, albumin, high density lipoprotein cholesterol, creatinine, fasting plasma glucose, C-reactive protein and N-terminal pro-brain natriuretic peptide.
  2. BMI body mass index.
