| acceptable daily intake | <pharmacology> This is an estimate of the amount of a substance in food that can be ingested daily over a lifetime by humans without appreciable health risk. The concept of the acceptable daily intake has been developed principally by who and FAO and is relevant to chemicals such as additives to foods, residues of pesticides and veterinary drugs in foods. Acceptable daily intakes are derived from laboratory toxicity data, and from human experiences of such chemicals when this is available, and incorporate a safety factor. The acceptable daily intake is thus an estimate of the amount of a substance in food that can be ingested over a lifetime by humans without significant risk to health (for contaminants in food and drinking water, tolerable intakes - daily or weekly - are used). See: tolerable daily intake. (15 Jan 1998) |

| activities of daily living | The things we normally do in daily living including any daily activity we perform for self-care (such as feeding ourselves, bathing, dressing, grooming), work, homemaking, and leisure. The ability or inability to perform ADLs can be used as a very practical measure of ability/disability in many disorders. (12 Dec 1998) |
| activities of daily living scale | A scale to score physical activity and its limitations, based on answers to simple questions about mobility, self-care, grooming, etc; widely used in geriatrics, rheumatology, etc. (05 Mar 2000) |
| daily dose | The total amount of a remedy that is to be taken within 24 hours. (05 Mar 2000) |
| tolerable daily intake | TDIs are applied to chemical contaminants in food and drinking water. The presence of contaminants is unwanted and they have no useful function, differing from additives and residues where there is or was deliberate use resulting in their presence. TDIs are calculated on the basis of laboratory toxicity data with the application of uncertainty factors. A TDI is therefore an estimate of the amount of a substance (contaminant) in food or drinking water that can be ingested daily over a lifetime without a significant health risk. (09 Oct 1997) |
| vital statistics | Used for general articles concerning statistics of births, deaths, marriages, etc. (12 Dec 1998) |
| national centre for health statistics | A centre in the public health service which is primarily concerned with the collection, analysis, and dissemination of health statistics on vital events and health activities to reflect the health status of people, health needs, and health resources. (12 Dec 1998) |
| statistics | The science and art of collecting, summarizing, and analyzing data that are subject to random variation. The term is also applied to the data themselves and to the summarization of the data. (12 Dec 1998) |
| statistics, nonparametric | A class of statistical methods applicable to a large set of probability distributions used to test for correlation, location, independence, etc. In most nonparametric statistical tests, the original scores or observations are replaced by another variable containing less information. An important class of nonparametric tests employs the ordinal properties of the data. Another class of tests uses information about whether an observation is above or below some fixed value such as the median, and a third class is based on the frequency of the occurrence of runs in the data. (12 Dec 1998) |
| descriptive statistics | Numerical values such as mean, median, and mode which describe the chief features of a group of scores, without regard to a larger population. (05 Mar 2000) |
| inferential statistics | Statistics from which an inference is made about the nature of a population; the purpose is to generalise about the population, based upon data from the sample selected from the population. (05 Mar 2000) |
| balsam, Canada | <microscopy> A resin from the balsam fir Abies balsamea. Dissolved in xylene, toluene, or benzene it is used as a mountant for permanent microscopical preparations. Its refractive index may vary from 1.530 to l.545 and its softening point from room temperature to 100deg.C, these properties varying with age and solvent content. If impure it discolours with age. See: lens, Bertrand. (05 Aug 1998) |
| canada | The largest country in north america, comprising 10 provinces and two territories. Its capital is ottawa. It was discovered by norsemen as early as 1000 a.d. And was the object of anglo-french rivalry in the 17th century, but by 1867 became one dominion. Canada is from an indigenous huron or iroquois word, kanata, meaning camp or village. The french explorers assumed this was the name of the entire country. (12 Dec 1998) |
| Canada balsam | A yellowish liquid resin from the balsam fir, Abies balsamea (family Pinaceae); contains kinene and bornyl acetate; used for mounting histologic specimens and as a cement for lenses. Synonym: Canada turpentine. (05 Mar 2000) |
| Canada snakeroot | An aromatic stimulant and diaphoretic. Synonym: Canada snakeroot, Indian ginger, wild ginger. (05 Mar 2000) |
