Adjusted R2 = 0.17.
Potential explanatory variables included pain at the donation site, lower back pain, difficulty sleeping, nausea or vomiting, light-headedness, fainting, bleeding at the donation site, infection at the donation site, and pain at the site of intravenous injection.
Backward stepwise variable selection was used to decide which variables to retain in the model. Explanatory variables were retained in the model when α was less than or equal to 0.10.
