Usage

Arguments

Format

A frame containing 241 observations on 13 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.
