  • The value given is calculated by dividing the number of sampling occasions preceding the occurrence of complications by the total number of sampling occasions for that individual. Thus if the total number of sampling occasions was 20 and bruising occurred after the 12th time, the value is 11/20 = 0.55. Values are expressed as median (range).
