As recognized because of the TRIDENT investigators, the study was confined by insufficient a placebo group and small sample dimension screening two distinctive doses. The TRIDENT study thus underscores the continuing have to have for scientific trials intended to Consider dosage regimens while incorporating cell dose ranges and perfectly-outlined affected individual populations with proper controls.
Nevertheless, there continues to be no proof that these types of therapies may be productive for accomplishing and retaining standard iron retail store degrees in TM people.
