Load and return assay of serum free light chain for 7874 subjects.
The dataset has 7874 samples and 9 features:
age: age in years sex: F=female, M=male sample.yr: the calendar year in which a blood sample was obtained kappa: serum free light chain, kappa portion lambda: serum free light chain, lambda portion flc.grp: the serum free light chain group for the subject, as used in the original analysis creatinine: serum creatinine mgus: whether the subject had been diagnosed with monoclonal gammapothy (MGUS) chapter: for those who died, a grouping of their primary cause of death by chapter headings of the International Code of Diseases ICD-9
age: age in years
sex: F=female, M=male
sample.yr: the calendar year in which a blood sample was obtained
kappa: serum free light chain, kappa portion
lambda: serum free light chain, lambda portion
flc.grp: the serum free light chain group for the subject, as used in the original analysis
creatinine: serum creatinine
mgus: whether the subject had been diagnosed with monoclonal gammapothy (MGUS)
chapter: for those who died, a grouping of their primary cause of death by chapter headings of the International Code of Diseases ICD-9
The endpoint is death, which occurred for 2169 subjects (27.5%).
See 1, 2 for further description.
x (pandas.DataFrame) – The measurements for each patient.
y (structured array with 2 fields) – death: boolean indicating whether the subject died or the event time is right censored.
futime: total length of follow-up or time of death.
