The Bradford Hill Criteria – Zoë Harcombe

WebThe Bradford-Hill criteria (J Roy Soc Med 1965:58:295-300) 1. Strength of the association. According to Hill, the stronger the association between a risk factor and outcome, the more likely the relationship is to be causal. 2. Consistency of findings. The Hill and Hill–Langmuir equations are used extensively in pharmacology to quantify the functional parameters of a drug and are also used in other areas of biochemistry. The Hill equation can be used to describe dose-response relationships, for example ion channel open-probability (P-open) vs. ligand … See more In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration. A ligand is "a substance that … See more The Hill coefficient is a measure of ultrasensitivity (i.e. how steep is the response curve).
