As you can see, the major effect of inflation is that a nation's nominal currency loses value - it takes more Dollars, or Pounds Sterling, or Euros, or Yen, or Swiss Francs, to buy the same quantity of goods. The obvious consequence, or effect, of this is that inflation makes it more difficult for people to afford the basic necessities, not to mention luxuries, of life if their labor is not able to keep pace with the inflation rate. This causes families to struggle as they attempt to keep up with the price of everything from cornflakes to college tuition.
Various medical scientists have studied possible trial effect ( clinical trial effect ) in clinical trials .    Some postulate that, beyond just attention and observation, there may be other factors involved, such as slightly better care; slightly better compliance/adherence ; and selection bias . The latter may have several mechanisms: (1) Physicians may tend to recruit patients who seem to have better adherence potential and lesser likelihood of future loss to follow-up . (2) The inclusion/exclusion criteria of trials often exclude at least some comorbidities ; although this is often necessary to prevent confounding , it also means that trials may tend to work with healthier patient subpopulations.
