WebNormally, using a arithmetic scale, the response curve is a hyperbolic, with most of the information squished together in a small section of the graph. By using the log the function usually becomes somewhat sigmoid, with a relatively linear section in the transition from low-high response. Web9 Apr 2024 · A dose response curve that has a standard slope, has a hill slope of 1.0, as the steepness of the graph increases the slope factor of the graph increases. The steepness of the curve is correlated with the potency of the drug. Steeper curves have maximal potency even at low drug concentration.
