first formula will be =SUMIFS($G$4:$G$21,$B$4:$B$21,$K4,$F$4:$F$21,L$2,$D$4:$D$21,1) , rest in the row are similar, and drag them down. Please see second sheet in attached. Thank you so much, you made my day!
Receiver operating characteristic curves were generated to determine the diagnostic accuracy of CDR-SB scores in classifying patients with MCI and dementia (all). Lastly, logistic regression was used with diagnostic group as the dependent variable and CDR-SB scores, as the independent variable, ...
