Description Usage Format Details References


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] preg parity, whether the subject had delivered a child.
[,8] race race of subject (Black or White only).
[,9] vol initial volume of fibroid.




A frame containing 240 observations on 9 variables.


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.
