Example: "In this study, we will analyze the results of the treatment group as comparator group to evaluate its effectiveness."
Alternatives: "as a reference group" or "as a control group".
In this analysis, we used the HIV-uninfected individuals with and without active TB as comparator groups that were enrolled in parallel, as reported in a previous study [34].
We used the ratio data to perform a receiver-operator characteristic (ROC) analysis, using the groups with and without active disease as comparator groups.
Based on these data, we performed a ROC analysis using the QFT-IT-negative cured TB subjects and the healthy controls as comparator groups.
To evaluate whether a prolonged test could improve the detection of LTBI, we set up the test using cured TB patients (with a microbiologically diagnosed past pulmonary disease) who resulted QFT-IT-negative and healthy controls as comparator groups.
Similar effects may possibly be observed in a population of survivors of serious illness who did not spend time in intensive care; future studies should perhaps enroll such populations as comparator groups.
Differences were also found between age-matched and size-matched wild-type trout groups (64 mRNAs), with unique mRNA differences for each of the wild-type groups when compared to domesticated trout (Wa: 114 mRNAs, Ws: 88 mRNAs), illustrating an influence of fish developmental stage affecting findings when used as comparator groups to other genotypes.
Since no control groups are available for the open-label extension phases, we have used external RA cohorts to serve as comparator groups so that the rates observed with abatacept are placed into context with comparable, real-world RA populations treated with DMARDs.
Asthma, diabetes, epilepsy, and migraine were chosen from the list of conditions in the CCHS as comparator groups for this study as they are conditions that can affect individuals throughout the life span and they are all chronic conditions that can be associated with episodic exacerbations that may require periodic acute treatment.
In order to analyze the performance of our test, a ROC curve was constructed with different cut-offs of percentage of IFN-γ secreting cells upon stimulation with ESAT-6/CFP-10 choosing M. tuberculosis-infected (active TB and latent TB infection) and healthy individuals as comparator groups.
Review included patients identified as exposed to rosiglitazone and with myocardial infarction (n = 50) or exposed and without an event (n = 50) as well as the comparator group of patients (receiving one of the other three oral diabetes medications but not exposed to rosiglitazone) and with (n = 50) or without myocardial infarction event (n = 50).
