rate
Etymology: L, ratus, reckoned
a numeric ratio, often used in the compilation of data concerning the prevalence and incidence of events, in which the number of actual occurrences appears as the numerator and the number of possible occurrences appears as the denominator. When 1 person in 15 fails an examination, the failure rate is said to be 1/15 (or "one in fifteen"). Standard rates are stated in conventional units of population such as neonatal mortality per 1000 or maternal mortality per 100,000.
rate,
n measurement of a thing by its ratio or given in relation to some standard.
rate, basal metabolic,
n See basal metabolic rate.
rate, DEF,
n an expression of dental caries experience in primary teeth. The DEF rate is calculated by adding the number of decayed primary teeth requiring filling (D), decayed primary teeth requiring extraction (E), and primary teeth successfully filled (F). Missing primary teeth are not included in the count because whether they were extracted because of caries or exfoliated normally is often impossible to determine.
rate, DMF index,
n a method of classifying the condition of the teeth based on the number of teeth in a given oral cavity that are decayed, missing, or indicated for removal and of those filled or bearing restorations.
rate, erythrocyte sedimentation
n the rate of settling of erythrocytes by gravity under conditions in which all factors affecting the rate are corrected, standardized, or eliminated except for alterations in the physicochemical properties of the plasma proteins. These alterations are the basis for interpretation of the rate. There is an increase in the rate in most infections. Sedimentation velocity is useful in prognosis to determine recovery from infection. Normal values vary with the method used in the determination.
rate, heart,
n the rate of the heartbeat, expressed as the number of beats per minute. The heart rate is reflected in the pulse rate. The cardiac rate of contraction is described as normal (70 beats/min), rapid (more than 100 beats/min), or slow (less than 55 beats/min). Disturbances in heart rate and rhythm may be paroxysmal or persistent. Descriptive terms are
tachycardia (increased, shallow heart rate to compensate for inadequate cardiac output) and
brady-cardia (slow, firm heart rate caused by cardiac sinus mechanisms and the vagal effect over the sympathetic innervation of the heart).
tachycardia (increased, shallow heart rate to compensate for inadequate cardiac output) and
brady-cardia (slow, firm heart rate caused by cardiac sinus mechanisms and the vagal effect over the sympathetic innervation of the heart).
rate, survival,
n the percentage of survivals within a certain study; in dentistry, it refers to the percentage of implants that are functioning within acceptable standards.

Q. How fast can primary amyloidosis spread? And what is the average survival rate for this disease?
A. Your best bet for one-stop shopping for amyloidosis information on the net is http://www.amyloidosis.org. There is also a Yahoo group named amyloidosis and also a mailing list named amyloid hosted by the Association of Cancer Online Resources. The amyloid list has around 500 subscribers, amyloidosis Yahoo group has maybe half that many. Face-to-face support for patients and caregivers is also available in most large metropolitan areas two or three times a year. See http://www.amyloidosissupportgroups.com for details.

Q. What is the rate of alcoholism in the USA compared to the rest of the world? What is the rate of alcoholism in the USA compared to other countries in the world. I don't mean amount of alcohol consumed, but alcohol addiction/dependency. Links to your sources would be appreciated. Cheers! (pun intended)
A. here is a link to a CDC table about drinking hobbits of Americans:

Q. I was wondering the rate at which alcohol induces brain damage. I am not an alcoholic and I use to drink only on weekends. I was wondering the rate at which alcohol induces brain damage; I know that over some years, damage occurs, but does anything happen after a month of drinking on weekends?
A. HI WAYLON;just want to add my two cents here,EVERYTIME YOU TAKE A DRINK IT KILLS BRAIN CELL,I CANT TILL YOU HOW MANY---mrfoot56
