Table 4 Results of Cox proportional hazards model comparing mortality in COPD patients free from CHF with relative lymphocyte count ≤20%
From: Relative lymphocyte count as an indicator of 3-year mortality in elderly people with severe COPD
Variable | Hazard ratio for relative lymphocytes count ≤20% (95% CI) | p-value |
|---|---|---|
Adjusted for age and sex | 1.65 (1.04–2.61) | 0.034 |
Adjusted for age, sex, smoking, body mass index, FEV1 (percent of predicted), FVC (percent of predicted), FEV1/FVC (percent), PaO2, PaCO2, pH, ischemic heart disease, history of myocardial infarction, heart rate, systolic and diastolic blood pressure. | 1.63 (1.03–2.58) | 0.038 |
