Logistic regression analysis of factors associated with influenza and pneumococcal vaccination in patients with chronic obstructive pulmonary disease.
| Factors | OR | 95% CI | P-value |
|---|---|---|---|
| Influenza vaccination | |||
| Pneumococcal vaccination | 923.10 | 0.01–1,032.73 | .997 |
| Pulmonologist | 1.74 | 0.64–4.68 | .276 |
| Every 1% increase in FEV1 after BD test | 1.07 | 1.01–1.14 | .045 |
| Pneumococcal vaccination | |||
| Heart disease | 1.74 | 0.47–6.51 | .409 |
| Lung disease | 5,674.01 | 0.01–12,047.37 | .999 |
| Influenza vaccination | 2,828.37 | 0.01–8,666.96 | .997 |
| Pulmonologist | 23.22 | 5.36–100.51 | <.001 |
| Every 1% predicted increase in post-BD FVC | 0.99 | 0.96–1.02 | .525 |
| Every 1 L increase in post-BD FEV1 | 0.87 | 0.15–4.94 | .871 |
| Every 1% increase in pre-BD FEV1/FVC | 0.95 | 0.89–1.01 | .075 |
| Every 1 unit increase in mMRC | 1.43 | 0.83–2.46 | .195 |
BD = bronchodilator, CI = confidence interval, FEV1 = forced expiratory volume in 1 second, FVC = forced vital capacity, L = liters, mMRC = modified Medical Research Council, OR = odds ratio.
