Variables associated with all-cause mortality among all patients in a Cox proportional hazard regression model
| Variables | Unadjusted | Fully Adjusted | ||
| HR (95% CI) | P values | HR (95% CI) | P values | |
| PA | 1.65 (1.01 to 2.72) | 0.048 | 3.07 (1.32 to 7.15) | 0.009 |
| Sex, M/F | 2.35 (1.46 to 3.78) | <0.001 | 2.21 (1.09 to 4.49) | 0.028 |
| Age | 1.08 (1.06 to 1.11) | <0.001 | 1.10 (1.06 to 1.14) | <0.001 |
| BMI | 0.86 (0.79 to 0.93) | <0.001 | 0.76 (0.68 to 0.86) | <0.001 |
| Onset of symptoms | 1.03 (1.01 to 1.04) | <0.001 | 1.02 (0.99 to 1.05) | 0.081 |
| mMRC score | 1.35 (1.24 to 1.47) | <0.001 | 1.04 (0.85 to 1.27) | 0.711 |
| LCQ score | 0.84 (0.78 to 0.90) | <0.001 | 1.00 (0.89 to 1.13) | 0.979 |
| FEV1% of predicted (%) | 0.98 (0.97 to 0.99) | 0.001 | 0.99 (0.98 to 1.01) | 0.185 |
Variables are adjusted for PA/non-PA status, sex, age, BMI, onset of symptoms, mMRC score, LCQ score and FEV1% of predicted (%).
BMI, body mass index; FEV1, forced expiratory volume in 1 s; LCQ, the Leicester Cough Questionnaire; mMRC, modified Medical Research Council; PA, Pseudomonas aeruginosa.
