“dose-response relationship” may represent a variety of things: it may refer to the shape of the exposure-outcome curve, no matter what that shape may be, or it may also imply that the objectives of a study assessing exposure-associated side effect are to demonstrate a continuous...
Dose–response models describe a cause–effect relationship. There are a wide range of mathematical models that have been used for this purpose. The complexity of a dose–response model can range from a simple one-parameter equation to complex multicompartment toxicokinetic/toxicodynamic models. Many...
Binary logistic regression analyzed the association between sedentary time and anxiety and the interaction effect of daily 10-min walks and sedentary time on anxiety. Restricted cubic spline model explored the dose–response relationship between sedentary time and anxiety risk. Results Participants who ...
Depending on the biological system and the experiment, defining the dose-response relationship and obtaining an accurate EC50 may require constraining parameters (fixing to a constant value). In the case of the Hill Slope, your dose-response analysis may yield accurate results by constraining the sl...
(dose-effect-relationship);以药物的剂量或浓度为横坐标 药物的效应和作用 作用(action):是指药物与机体组织间的初始作用；效应(effect):由于药物作用引起的机体在功能或形态上的变化。药物效应的分析 1.药物效应的基本表现1)兴奋(Stimulation):机体原有功能的增 强，如肾上腺素可使血压升高；2)抑制(Inhibition):...
The use of lipid-lowering drugs in the dialysis population has been controversial and there is no target for the dialysis population. To elucidate the dose-response relationship between lipids and all-cause mortality in the dialysis population. Computer
