What is a vehicle treated group?

Vehicle control groups are treated with the same solvent of the stock solution, which is used for test group. For example my test group is treated with 30microM concentration of a drug from stock solution of 10mM concentration for wich I have to take 2 microL of stock solution.

Randomized controlled trials cannot yield robust data unless they are planned, conducted, and analyzed in ways that are methodologically sound and appropriate to the question being asked.

Which is the best description of a controlled clinical trial?

A method of assigning patients to treatment and control groups that minimizes bias and assures comparability of the groups. Adequate measures to minimize bias, by the subjects, observers and the data analysts. Well-defined and reliable assessment of subjects’ response.

Are there any randomized, placebo-controlled clinical trials?

This randomized, double-blind, placebo-controlled clinical trial was approved by the Institutional Review Board at Busan National University Yangsan Hospital (IRB 02-2015-014).

Are there any clinical trials for ADSC-CE?

Accumulating evidence suggests that adipose-derived stem cell constituent extract (ADSC-CE) helps hair regrowth in patients with androgenetic alopecia (AGA). However, the effects of ADSC-CE have not been demonstrated in a randomized, double-blind, vehicle-controlled clinical trial.

How are control groups classified in a clinical trial?

Control groups in clinical trials can be classified on the basis of two critical attributes: (1) the type of treatment used and (2) the method of determining who will be in the control group.

Can a clinical subject participate in more than one clinical study?

Clinical test subjects can be participating in multiple clinical studies concurrently. However, it is the responsibility and duty of the test subject to notify both study facilitators for their approval and to ensure the patient safety as test subject.
