• ###### means
• If the proportional hazard assumption holds, a hazard ratio of one means equivalence in the hazard rate of the two groups, whereas a hazard ratio other than one indicates difference in hazard rates between groups. (wikipedia.org)
• A contrast ratio of 2,500:1, for example, means that the display is capable of displaying whites that are 2,500 times as bright as the darkest black. (reference.com)
• ###### close
• Mathematically if the change in the numerator is similar to the change in the denominator, the delta ratio will be close to 1. (wikipedia.org)
• ###### relative
• Hazard ratios differ from relative risks and odds ratios in that RRs and ORs are cumulative over an entire study, using a defined endpoint, while HRs represent instantaneous risk over the study time period, or some subset thereof. (wikipedia.org)
• A rate ratio (sometimes called an incidence density ratio) in epidemiology, is a relative difference measure used to compare the incidence rates of events occurring at any given point in time. (wikipedia.org)
• ###### Delta
• Since the anions are unable to diffuse out of the bloodstream, while bicarbonate and hydrogen ions diffuse with ease (as H₂CO₃, carbonic acid), the usual result will be closer to a delta ratio of 1 to 2. (wikipedia.org)

• ###### often
• When the two quantities are measured with the same unit, as is often the case, their ratio is a dimensionless number. (wikipedia.org)
• ###### large
• The existence of multiple theories seems unnecessarily complex to modern sensibility since ratios are, to a large extent, identified with quotients. (wikipedia.org)
• Second, the lack of a widely used symbolism to replace the already established terminology of ratios delayed the full acceptance of fractions as alternative until the 16th century. (wikipedia.org)
• ###### terms
• Ratios are sometimes used with three or more terms. (wikipedia.org)
• ###### study
• In its simplest form, the hazard ratio can be interpreted as the chance of an event occurring in the treatment arm divided by the chance of the event occurring in the control arm, or vice versa, of a study. (wikipedia.org)
• ###### origin
• It is impossible to trace the origin of the concept of ratio because the ideas from which it developed would have been familiar to preliterate cultures. (wikipedia.org)
• However, it is possible to trace the origin of the word "ratio" to the Ancient Greek λόγος (logos). (wikipedia.org)
