Note. First percentage in right column is based on total sample for cells where adverse event is reported; second percentage is based on all 241 subjects across all studies and assumes that investigators screened for that adverse event in all studies. Whereas neither percentage may be correct, we regard the first as more accurate, albeit possibly high.
