The phrase "appropriateness of control" is correct and usable in written English.
It can be used in contexts discussing the suitability or relevance of control measures or mechanisms in various situations, such as management, governance, or systems analysis.
Example: "The appropriateness of control in this project will determine its overall success and efficiency."
Alternatives: "suitability of oversight" or "relevance of regulation".
The objectives of the study were to compare (1) willingness to include vs. (2) willingness to prescribe control treatment among physicians randomized to assess, respectively, either (1) enrollment in a trial or (2) appropriateness of control treatment in a care context for the same fictional patient.
RCTs were more likely than observational studies to attain high scores in descriptions of appropriateness of control group, inclusion and exclusion criteria, study population, and the intervention protocol.
Recently, there has been a discussion in the literature of the most appropriate way to adjust for temperature when examining ozone-related mortality, as well as the appropriateness of controlling for ozone in studies of temperature-related mortality.
Although many studies do not control for ozone for unspecified reasons (e.g., Barnett 2007), in recent years some authors have argued that ozone or other pollutants may be on the causal pathway between temperature and mortality, and have questioned the appropriateness of controlling for it as a confounder on this basis (Goldberg et al. 2011; McMichael et al. 2008).
There are several additional issues other than the type I error inflation arising from PS to consider when evaluating the appropriateness of convenience controls versus controls selected to reflect the study-base that produced the cases.
The maximum closed-loop log modulus, Lc,max, is considered because it measures the robustness of the control systems and thereby can indicate the appropriateness of controller design with respect to the current operating condition.
Comparisons between the intervention and control groups in the pre-intervention period generally show similarities across a range of measures, indicating the appropriateness of the control group.
The appropriateness of various control methodologies for this problem will also be discussed.
