This data set contains a subset of the data from the Fibroid Growth Study.
[,1]
ID
ID for subject.
[,2]
fid
ID for fibroid (each women could have multiple fibroids).
[,3]
lfgr
log fibroid growth rate. See details.
[,4]
age
age category Younger, Middle, Older.
[,5]
loc
location of fibroid, corpus, fundus, or lower segment.
[,6]
bmi
body mass index of subject.
[,7]

[,8]
race

Usage
data(fibroid)
Format
A frame containing 240 observations on 9 variables.
Details
The response variable lfgr was calculated as the change in log fibroid volume,
divided by the length of time between measurements. The growth rates were averaged to produce
a single value for each fibroid, which was scaled to represent a 6-month percent change in volume.
