In statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values. In certain fields it is known as the look-elsewhere effect. The more inferences are made, the more likely erroneous inferences are to occur.

Why perform a meta-analysis? What is a meta-analysis? Meta-analysis is the statistical procedure for combining data from multiple studies.

Why Molecules Exist Independently One interpretation of these results is that, in healthy cells, a small proportion of the Bax molecules exists in a ‘primed’ state, presumably a conformer with the BH3 domain exposed but. (Hb)-related molecules exist to achieve this in a variety of species ranging from plants to humans.1 The process of life today is undoubtedly reliant on the continuous supply of oxygen to the cells throughout the body, tasked by car-diopulmonary systems, vasculature, and the liquid tissue called blood.
