There are four possible time moments for complication prediction: on base of the information known at 1. the time of admission to hospital: all input columns (2-112) except 93, 94, 95, 100, 101, 102, 103, 104, 105 can be used for prediction; 

2. the end of the first day (24 hours after admission to the hospital): all input columns (2- 112) except 94, 95, 101, 102, 104, 105 can be used for prediction;

 3. the end of the second day (48 hours after admission to the hospital) all input columns (2- 112) except 95, 102, 105 can be used for prediction;

 4. the end of the third day (72 hours after admission to the hospital) all input columns (2- 112) can be used for prediction
