  1. The baseline predicted follow-up diagnosis with tool compared to the follow-up diagnosis for all patients and stratified according to baseline SCD and MCI diagnosis. “Unchanged prediction” indicates patients where the prediction did not change after the PredictND tool was used, whereas in “changed prediction,” the baseline predicted follow-up diagnosis without tool was changed when applying the tool. Data are presented as mean ± SD or n (%). Difference between without and with tool confidence was assessed using paired-sample t tests
  2. Abbreviations: WOT without tool, WT with tool, Δ difference confidence the difference between confidence in the prediction without and with tool, VAS visual analogue scale from 0 to 100%
  3. *Significant increased confidence after using the PredictND tool, p < 0.05
