Yo no me preocuparía por traducir "realized",... ...sino que diría que «la intensidad de dosis relativa (IDR) es una medida de la cantidad de fármaco recibida en un determinado período de tratamiento, expresada como un porcentaje de la cantidad prevista para dicho periodo» o «...un porcentaje de la cantidad teórica correspondiente a dicho período».

O pensándolo mejor, en vez de "cantidad" diría "dosis total". Es decir, «la intensidad de dosis relativa (IDR) es una medida de la dosis total de fármaco recibida en un determinado período de tratamiento, expresada como un porcentaje de la dosis total prevista para dicho periodo» o «...un porcentaje de la dosis total teórica correspondiente a dicho período».

Mirá cómo definen la IDR en estos dos textos (uno en inglés y otro en castellano):

another hard one Looking for your phrase online, I find it only in a few references from this article that you're translating. I think that in this sentence, the authors are using the word "realize" in one of its possible -- but not common -- English usages: "to bring (a plan, ambition, etc.) to fruition; make actual or concrete." In other words, it means here what the Spanish "realizar" usually means ... to carry out or perform something. So as I understand it, they're saying that this relative dose-intensity measurement shows the amount of drug received as a percentage of the amount of drug that was planned/scheduled to be given during this period in which the patient did actually receive treatment (the period in which the treatment was really given/administered).

I can't see that "realized" here could be translated as "verificado" or "corroborado" but something with "realizado" sounds like a good possibility to me.

Let's see what our colleagues think.
