Bias is an error in the design, conduct, or analysis of a study that results in a deviation of the test statistic from its true value. This results in an
Survivorship biasoccurs when you do not evaluate your data set in its entirety: for example, by only analyzing the patients who survived a clinical trial. This strongly increases the likelihood that you draw (incorrect) conclusions based upon those who have passed some sort of selection process—...
Investigations of the effect of placebo are often challenging to conduct and interpret. The history of placebo shows that assessment of its clinical significance has a real potential to be biased. We analyze and discuss typical types of bias in studies on placebo. A methodological analysis and dis...
The clinical part of the curriculum has a modular structure: There are 21 modules lasting two to seven weeks each; the sequence of modules is identical for all students. Thus, all students take part in a six-week, interdisciplinary cardio-respiratory module at the beginning of year four. Two...
We attempted to minimize the bias by subtracting it from the maximum RMS value of each target muscle. The highest RMS value was defined as the maximum RMS value among the 10 RMS values (1-s section) measured for each exercise maneuver18. In addition, the average RMS value was calculated ...
clinical trials have risen sharply in recent years. Indirectly, individuals support medical science every day through taxes they pay as well as products and services they purchase from companies. For example, something as simple as buying a bottle of aspirin may helpfoot the bill formedical ...
Consistent detection of cell types responsible for drug metabolism (for example, liver and renal cell types) as well as cell types that are drug targets, such as neurons or oligodendrocytes for Alzheimer’s-protective drugs, could provide strong clinical trial endpoint data when evaluating drug ...

pathogenic at the RNA level through splicing alterations, and these mutations are often located in the splicing donor, acceptor, and intronic regions. Consequently, splicing alterations have also been considered for the pathogenicity evaluation of mutations [18,19]. However, in clinical practice of ...
