  5. (Confounding) The distortion of a measure of the effect of an exposure (eg to therapy involving the proposed drug) on the risk of an outcome under investigation brought about by the association of the exposure with other factor(s) that can influence the outcome. ...
  6. (confounding) Allowing two or more variables to vary together so that it is impossible to separate their unique effects.
  7. (Confounding) When the differences between the treatment and control groups other than the treatment produce differences in response that are not distinguishable from the effect of the treatment, those differences between the groups are said to be confounded with the effect of the treatment (if ...

  15. A factor that is related to one or more of the variables being studied. Confounders can increase or decrease the apparent effectiveness of a treatment. Randomization is designed to create equal numbers of confounding factors in all groups. ...
  16. a factor that can influence a trial or experiment, leading to unexpected outcomes that improperly skew the results.
  17. A factor that is associated with both an intervention (or exposure) and the outcome of interest. For example, if people in the experimental group of a controlled trial are younger than those in the control group, it will be difficult to decide whether a lower risk of death in one group is due to ...
