#Numeric variables are presented as mean (standard deviation).
##Statistical differences were assessed using the Wilcoxon test.
*Accuracy was considered when pREE fell between 90 and 110% of mREE (individual level).
†(%) represents the percentage mean of the difference between pREE and mREE (group level).
