Yet, despite considerable variability in study design, most rodent studies suggest a protective role for androgens at several stages of experimental breast cancer.
The results of several recent large well designed population-based studies suggest that the lymphoma risk associated with azathioprine and 6-mercaptopurine therapy is likely to be of minimal clinical significance compared to the established and more frequent risks of myelosuppression and infection, and is far outweighed by the clinical benefit of immunomodulator therapy in IBD.
Further, the unique designs of sequencing studies suggest that a single black box approach is unlikely to be uniformly optimal across all experiments.
With respect to sibling designs specifically, twin studies suggest a moderate degree of overlap in genetic influences on ASD and ADHD traits, whether in the general population or in samples with clinically elevated symptoms [ 120– 120].
Variability in definition of periodontal disease, as well as design flaws in published studies, suggest that the available findings should be viewed with caution (overall Grade C evidence).
Our studies suggest a design principle that can be employed by polarity networks: short-range mutual inhibition establishes distinct signaling regions, after which directed long-range activation insulates one region from variations in the other.
Within the limits of a pre-post design, study findings suggest that anthroposophic therapies are not associated with a relevant increase in total health costs.
Analysis of the design of some studies suggests that the lack of agreement between EIA and conventional assays may depend on the diagnosis and/or the selection bias of the patients under study [ 2- 4, 6].
Contrary to the conventional practice which adopts ICU optimization as the key element of gene design, our study suggests that CC fitness is a more relevant design parameter for optimizing the sequence for improved heterologous protein expression.
Additionally, we make specific recommendations for designing studies and suggest a method for determining whether engineering and administrative controls or individual-level interventions would be of most benefit to an overexposed group of workers.
