Validity of the Results

Having defined the objectives for a trial, we must consider the validity of any results we may obtain. One dictionary definition of validity is “so executed etc. as to have binding force” [55]. A trial result may not have binding force when executed incorrectly or when the trial provides a certain result but the interpretation of that result is incorrect. An incorrect interpretation can arise when the trial reveals a particular result and the investigator jumps to a further conclusion or when he decides that the same result will be true in different subjects.
