| dose-response curve | This is a graph to show the relation between the dose of a drug or other chemical and the degree of response it produces, as measured by the percentage of the exposed population showing a defined, often quantal, effect. (09 Oct 1997) |

| dye-dilution curve | Graph of the serial concentrations (dilutions) of a dye, e.g., Evans blue, following its intravascular or intracardiac injection; useful in the diagnosis of congenital cardiac shunts, measurement of cardiac output, and detection of cardiovalvular incompetence. Synonym: indicator-dilution curve. (05 Mar 2000) |

| intracardiac pressure curve | Curve of pressure recorded within the atrium or ventricle (intra-atrial and intraventricular pressure curve's). (05 Mar 2000) |
| isovolume pressure-flow curve | The relationship between transpulmonary pressure and respiratory air flow, expressed as a function of lung volume. (05 Mar 2000) |
| tension curve | The direction of the trabeculae in cancellous bone tissue adapted to resist stress. (05 Mar 2000) |
| epidemic curve | A graph in which the number of new cases of a disease is plotted against an interval of time to describe a specific epidemic or outbreak. (05 Mar 2000) |
| flow-volume curve | The graph produced by plotting the instantaneous flow of respiratory gas against the simultaneous lung volume, usually during maximal forced expiration. (05 Mar 2000) |
| force-velocity curve | The relationship between isotonic velocity of shortening and afterload for a contracting muscle. (05 Mar 2000) |
| Frank-Starling curve | A graph in which cardiac output or stroke volume is plotted against mean atrial or ventricular end-diastolic pressure; with increasing venous return and atrial pressure the output proportionately increases until further increments overload the heart and the output falls. Synonym: Frank-Starling curve. (05 Mar 2000) |
| frequency curve | A systematic grouping of data into classes or categories according to the frequency of occurrence of each successive value or ranges of such values, resulting in a graph of a frequency distribution. Synonym: frequency curve. (05 Mar 2000) |
| Friedman curve | A graph on which hours of labour are plotted against cervical dilation in centimeters. (05 Mar 2000) |
| logistic curve | An S-shaped curve which depicts the growth of a population in an area of fixed limits. (05 Mar 2000) |
