That depends on what the patient regards as severe anemia, and whether or
not objectively, any data has been collected.  Otherwise your question would
be best answered in an ancedotal remark such as in my case.  I suffered
severe anemia, because it knocked me on my a.s like nothing ever before.  I
suspect any data would be more than collected acedotal comment, in any
study.

I'm not sure what borders "severe anemia". I had it bad enough, though 1/2
way through it bounce up a bit on the Hemoglobin. I couldn't do much for
very long and was tired all the time.
