Toenail infection treatment study
Description
The data come from a Multicenter study comparing two oral treatments for
toenail infection. Patients were evaluated for the degree of separation of
the nail. Patients were randomized into two treatments and were followed
over seven visits - four in the first year and yearly thereafter. The
patients have not been treated prior to the first visit so this should be
regarded as the baseline.
Format
A data frame with 1908 observations on the following 5 variables.
- ID
ID of patient
- outcome
0=none or
mild seperation, 1=moderate or severe
- treatment
the
treatment A=0 or B=1
- month
time of the visit (not exactly
monthly intervals hence not round numbers)
- visit
the number
of the visit
