A control is a comparison. In an experiment, you test a hypothesis by adjusting something - an independent variable. A control is something you put through the same procedure, without adjusting that independent variable. You can then compare the results of the control to the other results of t...
All 10 randomly selected 1:2 control cohorts were matched on propensity score which included age, sex, race, and hypertension and edema diagnosis. Two-sided χ2 test, df = 1, χ2 values shown, all P < 0.05, unadjusted p-values shown. b, AD prevalence in bumetanide-exposed cohort ...
along with a12C-labeled straw addition and no straw treatments serving as isotopic control and background, respectively (Fig.1). The overall priming effect was positive for the control samples, with 121.1 ± 10.4 μg C/g soil ...
(Mo, Z = 42, EKα = 17.48 keV) solid disk or foils of 100 mm diameter and of variable thickness. Note that a fresh target surface is provided for each laser shot. At 45° incidence angle, laser absorption through vacuum heating mechanism is optimized when the pre-plasma ...
The distinctive aspect of our approach is that we regulate the thickness of the bottom layer to enhance the imaging performance while maintaining the thickness of the top layer to control the reflectance. In addition, the low refractive index of Ru is expected to enable the guiding of light ...
Subsequently, the same MNX mouse strains were crossed to male FVB/N-Tg(MMTVneu) mice, which overexpress the wild-type Her2/neu oncogene under the control of the MMTV promoter [91]. Tumor latency and metastases were quantified. Results in FF and FC progeny were similar to those seen in the...
Process variables are factors that are not part of the mixture, although when the levels are variable, it can affect the mixture properties. Process variables such as the particle size of tire rubber, are independent and can change without restriction [20]. The most frequently used models which...
The CILP-2 competitive assay had an intra assay variation of 11.1% and the inter assay variations for high control was 20.7% and for low control 22.2%. All analyses were carried out without any prior knowledge of the individual samples. Statistical analysis Quantitative variables are expressed as...
These SCFAs are involved in the pathophysiology of obesity and related disorders by affecting the control of body weight via energy intake and energy harvesting, maintaining intestinal homeostasis, and linking with insulin sensitivity through the inflammatory response, lipid storage and adipose tissue ...
The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The i
