You’d have to know a lot about each case to make a determination.
The general health of the idividual
The lag time after infection
The relative stage treatment started in
The methods used to treat
This is still so new that people can try different things. There’s probably not rock solid protocol yet.

In addition to the short list you provided...there is one additional consideration which complicated Duncan's situation - 'CONSENT'. Because there was no blood relation at the hospital, the family members who were with Louise Troh are upset because none of them had legal standing to offer consent for treatment. see here
Duncan dug his own grave by lying directly and indirectly, by omission. Had he fessed up about his direct contact with Ebola to the triage nurse or to his family he would have had a fighting chance to survive.
Duncan is fully responsible for his own demise.
