What does "cannot be determined" mean?
The words "cannot be determined" mean that the better research found that one type of care involves more risk than another, but the size of the difference cannot be described with numbers due to the way the research was carried out. In some cases, which are noted, the difference cannot be determined because studies disagreed.
