Endvidere blev der også gennemført fire undersøgelser, hvori man sammenlignede en kombination af begge aktive stoffer med hvert enkelt stof alene hos patienter, som aldrig var blevet behandlet, og patienter, hvis blodsukkerniveauer ikke var under kontrol, når de blev behandlet med kun et af stofferne.
In addition, four studies were carried out, comparing the combination of both active substances to each substance on its own, in patients who had never been treated, as well as in patients whose blood glucose levels were not controlled when treated with only one of the substances.
