1	data(QoLdata)

id: patient identification number
time: visit number for quality of life assessment, in this case all measurements are from the first time-point (hence, all are set to 0)
date: date of quality of life measure
QoL: score of global quality of life on a 0-1 scale in order that a high score reflects a high quality of life level
pain: score of pain on a 0-100 sale in order that a high score reflects a high level of pain
arm: treatment arm equal to 0 or 1

## take one time-point

## remove missings
dataqol <- dataqol[complete.cases(dataqol[,c("QoL", "arm", "pain")]),]
## rescale outcome to [0,1]
dataqol$QoL <- dataqol$QoL/100
