| B | bias |
| bias | <statistics> In a clinical trial, bias refers to effects that a conclusion that may be incorrect as, for example, when a researcher or patient knows what treatment is being given. To avoid bias, a blinded study may be done. Any deviation of results or inferences from the truth, or processes leading to such deviation. Bias can result from several sources: one-sided or systematic variations in measurement from the true value (systematic error); flaws in study design; deviation of inferences, interpretations, or analyses based on flawed data or data collection; etc. There is no sense of prejudice or subjectivity implied in the assessment of bias under these conditions.

|---|---|
| publication bias | The influence of study results on the chances of publication and the tendency of investigators, reviewers, and editors to submit or accept manuscripts for publication based on the direction or strength of the study findings. Publication bias has an impact on the interpretation of clinical trials and meta-analyses. Bias can be minimised by insistence by editors on high-quality research, thorough literature reviews, acknowledgement of conflicts of interest, modification of peer review practices, etc. (12 Dec 1998) |
| selection bias | The introduction of error due to systematic differences in the characteristics between those selected and those not selected for a given study. In sampling bias, error is the result of failure to ensure that all members of the reference population have a known chance of selection in the sample. (12 Dec 1998) |
| insurance selection bias | Adverse of favourable selection bias exhibited by insurers or enrollees resulting in disproportionate enrollment of certain groups of people. (12 Dec 1998) |
| internal bias | Applied to the motile behaviour of crawling cells that, in the short term, show persistence and do not behave as true random walkers. Any intrinsic regulation of the random motile behaviour of the cell could be considered as internal bias. (18 Nov 1997) |
| block design test | A performance test using coloured blocks which the individual must use to match pictured designs; one of the subtests of the Wechsler intelligence scales. (05 Mar 2000) |
| rational drug design | <pharmacology> Modeling the molecular structure of the target of a drug, for example, an antigen, and then designing a drug that will attack it. (17 Dec 1997) |
| research design | A plan for collecting and utilizing data so that desired information can be obtained with sufficient precision or so that an hypothesis can be tested properly. (12 Dec 1998) |
| computer-aided design | The use of computers for designing and/or manufacturing of anything, including drugs, surgical procedures, orthotics, and prosthetics. (12 Dec 1998) |
| prosthesis design | The plan and delineation of prostheses in general or a specific prosthesis. (12 Dec 1998) |
| hospital design and construction | The architecture, functional design, and construction of hospitals. (12 Dec 1998) |
| software design | Specifications and instructions applied to the software. (12 Dec 1998) |
| dental prosthesis design | The plan and delineation of dental prostheses in general or a specific dental prosthesis. It does not include denture design. The framework usually consists of metal. (12 Dec 1998) |
| denture design | The plan, delineation, and location of actual structural elements of dentures. The design can relate to retainers, stress-breakers, occlusal rests, flanges, framework, lingual or palatal bars, reciprocal arms, etc. (12 Dec 1998) |
| design | 1. A preliminary sketch; an outline or pattern of the main features of something to be executed, as of a picture, a building, or a decoration; a delineation; a plan. 2. A plan or scheme formed in the mind of something to be done; preliminary conception; idea intended to be expressed in a visible form or carried into action; intention; purpose; often used in a bad sense for evil intention or purpose; scheme; plot.

(Locke) "How little he could guess the secret designs of the court!" (Macaulay) 3. Specifically, intention or purpose as revealed or inferred from the adaptation of means to an end; as, the argument from design. 4. The realization of an inventive or decorative plan; especially, a work of decorative art considered as a new creation; conception or plan shown in completed work; as, this carved panel is a fine design, or of a fine design. 5. The invention and conduct of the subject; the disposition of every part, and the general order of the whole. Arts of design, those into which the designing of artistic forms and figures enters as a principal part, as architecture, painting, engraving, sculpture. School of design, one in which are taught the invention and delineation of artistic or decorative figures, patterns, and the like. Synonym: Intention, purpose, scheme, project, plan, idea. Design, Intention, Purpose. Design has reference to something definitely aimed at. Intention points to the feelings or desires with which a thing is sought. Purpose has reference to a settled choice or determination for its attainment. "I had no design to injure you," means it was no part of my aim or object. "I had no intention to injure you," means, I had no wish or desire of that kind. "My purpose was directly the reverse," makes the case still stronger. "Is he a prudent man . . . That lays designs only for a day, without any prospect to the remaining part of his life?" (Tillotson) "I wish others the same intention, and greater successes." (Sir W.
