| recurrence rate | In genetic counseling, the risk that a future offspring will be affected given some specific set of relatives of whom at least one is already affected. (05 Mar 2000) |
|---|---|
| case fatality rate | The proportion of individuals contracting a disease that die of that disease. (05 Mar 2000) |
| maternal death rate | The number of maternal deaths that occur as the direct result of the reproductive process per 100,000 live births. See: rate. See: maternal death. (05 Mar 2000) |
| maternal mortality rate | The number of maternal deaths related to childbearing divided by the number of live births (or by the number of live births + foetal deaths) in that year. The maternal mortality rate in the united states in 1993 (and 1994) was 0.1 per 1,000 live births, or 1 mother dying per 10,000 live births. (12 Dec 1998) |
| glomerular filtration rate | <nephrology> Measure of the kidneys' ability to filter and remove waste products. (09 Oct 1997) |
| repetition rate | The number of pulses per minute, describing an energy outpute.g., ultrasound pulses in echocardiography rather than vascular pulses. (05 Mar 2000) |
| volume loading rate | The rate of raw materials put into a fermenter or aerobic digester, expressed in terms of material weight per unit volume per unit time. (09 Oct 1997) |
| respiration rate | Frequency of breathing, recorded as the number of breaths per minute. (05 Mar 2000) |
| respiratory rate | The number of breaths per minute (or, more formally, the number of movements indicative of inspiration and expiration per unit time). In practice, the respiratory rate is usually determined by counting the number of times the chest rises (or falls) per minute. By whatever means, the aim is to determine if the respirations are normal, abnormally fast (tachypnea), abnormally slow (technically termed bradypnea), or nonexistent (apnea). (12 Dec 1998) |
| response rate | <oncology> The percentage of patients showing partial or complete response to the given treatment. (16 Dec 1997) |
| per capita rate | <epidemiology> A rate which is proportional to the number of individuals in a population. (05 Dec 1998) |
| perinatal mortality rate | The number of stillborn infants of 24 completed weeks or more plus the number of deaths occurring under 7 days of life divided by the number of stillborn infants of 24 weeks or more gestation plus all liveborn infants in the same population, regardless of the period of gestation. (05 Mar 2000) |
| metabolic clearance rate | Volume of biological fluid completely cleared of drug metabolites as measured in unit time. Elimination occurs as a result of metabolic processes in the kidney, liver, saliva, sweat, intestine, heart, brain, or other site. (12 Dec 1998) |
| gross reproduction rate | The average number of female children a woman would have if she survived to the end of her childbearing years and if, throughout that period, she were subject to a given set of age-specific fertility rates and a given sex ratio at birth; this rate provides a measure of the replacement fertility of a population in the absence of mortality. (05 Mar 2000) |
| growth rate | <biology, cell culture, ecology> The rate, or speed, at which the number of organisms in a population increases. This can be calculated by dividing the change in the number of organisms from one point in time to another by the amount of time in the interval between the points of time. The phrase is most often used to describe growth of cells or microorganisms in laboratory cultures and usually expressed as the generation time. (21 Jun 2000) |
