Arguments
age |
Patient age, in years |
male |
A binary variable with 0 for females and 1 for males |
fvc |
FVC percent predicted in the current year (0-150) |
fev1 |
FEV1 percent predicted in the current year (0-150) |
fev1LastYear |
FEV1 percent predicted in the preceding year (0-150) |
bcepacia |
A binary with 0 for no B. cepacia complex and 1 for B. cepacia complex |
underweight |
A binary with 1 for underweight (BMI < 18.5 if age >= 19 or BMI percentile <= 12% if age < 19) |
nHosp |
An integer number of hospitalizations in preceding year |
pancreaticInsufficient |
A binary taking 1 for pancreatic insufficient status and 0 otherwise |
CFRelatedDiabetes |
A binary variable for CF related diabetes |
ageAtDiagnosis |
