| Cummer's classification | A listing of several types of removable partial dentures in accordance with the distribution of direct retainers. (05 Mar 2000) |
| Salter-Harris classification of epiphysial plate injuries | The classification of epiphysial plate injuries into five groups (I to V), according to the pattern of damage to epiphysis, physis, and/or metaphysis; the classification correlates with different prognoses regarding the effects of the injury on subsequent growth and subsequent deformity of the epiphysis. (05 Mar 2000) |
| horizontal classification | <zoology> Classification which stresses grouping together taxa in a similar stage of evolution, rather than location on the same phyletic line. See: Vertical classification. (09 Jan 1998) |
| natural classification | <zoology> Classification based on inferences concerning the phylogenetic relationships of animals. (09 Jan 1998) |
| New York Heart Association classification | A functional classification to assess cardiovascular disability. Class I: patients with cardiac disease without limitation of physical activity. Ordinary activity does not cause symptoms. Class II: patients with cardiac disease with slight limitation of activity; comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea or angina. Class III: patients with cardiac disease producing marked limitation of activity: comfortable at rest. Less than ordinary physical activity causes symptoms. Class IV: patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms may be present even at rest. (05 Mar 2000) |
| DeBakey's classification | Consists of three types: Type I extends into the transverse arch and distal aorta and type II is confined to the ascending aorta. Type III dissections begin in the descending aorta, with type IIIA extending toward the diaphragm and type IIIB extending below it. (05 Mar 2000) |
| Denver classification | A system of nomenclature for human mitotic chromosomes, based on length and position of the centromere. Origin: Denver,, Colourado, where agreed upon (05 Mar 2000) |
| Dukes' classification | A classification of the extent of operable adenocarcinoma of the colon or rectum commonly modified as follows: A (Duke's A), confined to the mucosa; B1, into the muscularis mucosae; B2, through the muscularis mucosae; C1, limited to the bowel wall, with nodal metastases; C2, through the bowel wall, with nodal metastases.

| International Classification of Disease | The classification of specific conditions and groups of conditions determined by an internationally representative expert committee that advises the World Health Organization, which publishes the complete list in a periodically revised book, the Manual of the International Statistical Classification of Diseases, Injuries and Causes of Death. The Tenth Revision (ICD) came into use in 1992; it has 20 chapters, each with a hierarchical arrangement of subdivisions (rubrics); some chapters are aetiological, more relate to body systems, some to classes of conditions, some to procedures. Acronym: ICD (05 Mar 2000) |
| International Classification of Health Problems in Primary Care | A classification of diseases, conditions and problems arranged for use in primary care where diagnostic precision is seldom possible. (05 Mar 2000) |
| International Classification of Impairments Disabilities and Handicaps | A WHO-sponsored numerical taxonomy of the impairments, disabilities and handicaps consequent upon injury and disease. (05 Mar 2000) |
| International Labour Organization Classification | ILO 1980 International Classification of Radiographs of the Pneumoconioses; a system for qualitative and semiquantitative description of the chest radiographic findings caused by pneumoconiosis, designed for epidemiologic studies; supersedes classifications of 1950, 1958, 1968, and 1971. (05 Mar 2000) |
| Tessier classification | An anatomical classification of facial, craniofacial, and laterofacial clefts that utilises the orbit as the primary structure for reference. Fifteen locations for clefts are differentiated. (05 Mar 2000) |
| E classification | <biochemistry> Classification of enzymes based on the recommendations of the Committee on Enzyme Nomenclature of the International Union of Biochemistry. The first number indicates the broad type of enzyme (1 = oxidoreductase, 2 = transferase, 3 = hydrolase, 4 = lyase, 5 = isomerase, 6 = ligase (synthetase)). The second and third numbers indicate subsidiary groupings and the last number, which is unique, is assigned arbitrarily in numerical order by the Committee. (08 Mar 2000) |
