Description:

This is a stratified random sample containing 1/2 of the subjects from a study of the relationship between serum free light chain (FLC) and mortality. The original sample contains samples on approximately 2/3 of the residents of Olmsted County aged 50 or greater.

Variables:

A data frame with 7874 persons containing the following variables.

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 FLC group for the subject, as used in the original analysis

creatinine

serum creatinine

mgus

1 if the subject had been diagnosed with monoclonal gammapothy (MGUS)

futime

days from enrollment until death. Note that there are 3 subjects whose sample was obtained on their death date.

death

0=alive at last contact date, 1=dead
