The phrase "administered variable" is correct and usable in written English.
It can be used in contexts related to research, statistics, or experimental design where a variable is manipulated or controlled by the researcher.
Example: "In the study, the administered variable was the dosage of the medication given to participants."
Alternatives: "controlled variable" or "manipulated variable".
In this paper we discuss the application of a MDT-based approach to administer variable-length tests in order classify examinees into a limited number of discrete categories.
Lisuride has been administered at variable dosages from 0.075 to 0.400 mg/day to patients with episodic and chronic cluster headache in an open study.
24 This previous study lacked blinding and allocation concealment, administered a variable number of injections, included participants with unilateral and bilateral symptoms, and had a high dropout rate.
Each patient was administered a variable number of ECT sessions, according to the individual clinical needs evaluated by experienced clinicians (Table 2).
To test whether FS also mitigates these effects when administered at variable times post radiation challenge, we delayed the dietary administration (0, 2, 4, 6 weeks) and evaluated BAL at 4 months post-XRT.
89Zirconium-labelled RG7356 (1 mg; 37 MBq) was administered after a variable dose of unlabelled RG7356 (0 to 675 mg).
Briefly, a primed-continuous infusion of regular insulin ( 1 or 3 milliunits/kg·min) was administered, and a variable infusion of a 25% dextrose solution was started and periodically adjusted to clamp the plasma glucose concentration at 7 8 mM.
For this reason, we subcutaneously administered insulin at variable rates and simultaneously sampled ISF glucose directly from the administration site.
In order to account for a possible effect of the way the test was administered, an indicator variable was included in the regression models for this test.
For continuous variables that were only measured twice, an analysis of covariance (ancova) model was used, with the change from baseline to endpoint as the dependent variable and treatment group, corresponding baseline value and number of OADs administered, as independent variables.
