Table 4.
Linear regression models of FEV1 % predicted among white patients. Results are presented as difference between the US-UK of FEV1 % predicted (95% CI).
| Number of patients in model | Adjusted US-UK effect (95% CI) | |
|---|---|---|

| ||
| Model 1: Adjusted for age at encounter | N=22867 | 3.31 (2.65, 3.96) |
|

| Model 2: Adjusted for age at encounter, gender, age at diagnosis, pancreatic sufficiency and genotype | N=22591 | 3.03 (2.37, 3.69) |
|

| Model 3: Adjusted for age at encounter, gender, age at diagnosis, pancreatic sufficiency, genotype, chronic Pseudomonas infection, chronic MSSA infection, B. cepacia infection and MRSA infection | N=22276 | 3.85 (3.17, 4.53) |
