Was enttäuscht, der Preiselbeersaft oder das Cochrane-Review?

Dass Cochrane-Reviews nicht immer Goldstandard sind, haben wir kürzlich an Beispielen gezeigt ([4], [5]). Auch das Review »Cranberries for preventing urinary tract infections« ([12]) kann nicht unkommentiert bleiben. Denn die darauf Bezug nehmende Meldung »Cranberry-Saft enttäuscht bei Harnwegsinfekten« in Heft 1/2013 der ZPT (S. 35) geht überhaupt nicht auf den Cranberry-Wirkstoff ein und darauf, dass die Zubereitungen aus der Preiselbeere in den eingeschlossenen Studien des Cochrane-Reviews unterdosiert gewesen sein könnten.
