Research synthesis or evidence synthesis is the process of combining the results of multiple primary research studies aimed at testing the same conceptual hypothesis. It may be applied to either quantitative [1] or qualitative research. [2] Its general goals are to make the findings from multiple different studies more generalizable and ...
This would mean that only methodologically sound studies should be included in a meta-analysis, a practice called 'best evidence synthesis'. [104] Other meta-analysts would include weaker studies, and add a study-level predictor variable that reflects the methodological quality of the studies to examine the effect of study quality on the effect ...
The prefixes ortho, meta, and para are all derived from Greek, meaning correct, following, and beside, respectively. The relationship to the current meaning is perhaps not obvious. The ortho description was historically used to designate the original compound, and an isomer was often called the meta compound.
Retrosynthetic analysis was used as early as 1917 in Robinson's Tropinone total synthesis. [1] Important conceptual work on retrosynthetic analysis was published by George Vladutz in 1963 . [ 2 ] [ 3 ] E.J. Corey formalized and popularized the concept from 1967 onwards in his article General methods for the construction of complex molecules and ...
Meta-analysis is a method used to combine the results of different trials in order to obtain a quantitative synthesis. The size of individual clinical trials is often too small to detect treatment effects reliably. Meta-analysis increases the power of statistical analyses by pooling the results of all available trials.
Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...
Metascience (also known as meta-research) is the use of scientific methodology to study science itself. Metascience seeks to increase the quality of scientific research while reducing inefficiency.
In organic chemistry, meta indicates the positions of substituents in aromatic cyclic compounds. The substituents have the 1,3-positions, for example in resorcinol. Meta may also denote the dehydrated form of an acid, salt or organic derivative in a series. For example: metabisulfite: 2 bisulfite (HSO − 3) → 1 metabisulfite (S 2 O 2− 5 ...
