Notes

  1. Patientid has duplicated numbers. I assume each row represent one independent observation.
  2. DCI as outcome

Boxplots

ROC curve - to predict DCI (0/1)

1. single marker: sFlt1

2. single marker: sEng

3. combined sFlt1 and sEng

4. best cut off

Best cutoff to predict DCI (0/1) is CSF sFlt1 day 6 > 136.8.
