Many words that are used interchangeably in common language take on different meanings when used in the context of medicine. This guide serves to highlight words that are commonly found on WikiDoc to be used incorrectly and to provide more appropriate alternatives. Like all aspects of WikiDoc, this page should be updated as more examples are found.

Words Mistakenly Interchanged

Incidence vs. Prevalence

Both incidence and prevalence are often used to mean the same thing in common language. In medicine, however, they have two distinct meanings. The definition of each term, as well as an example of each, is provided below.

Term Definition Example
Incidence The rate of occurrence or influence. Especially, the rate of occurrence of new cases of a particular disease in a population being studied New cases of Disease X are becoming less common among people over the age of 80 with an incidence of 1000 cases per year in the United States.
Prevalence The percentage of a population that is affected with a particular disease at a given time Disease X still affects a large portion of the population over the age of 80, being prevalent in 13% of this population.

Trial vs. Study

Use of the word trial versus study / analysis: Results of randomized observations can be referred to as a “trial”. Results of non-randomized observations should be referred to as studies or analyses.

Term Definition Example
Study A careful examination or analysis of a phenomenon, development, or question. A recent study examined the association between patients taking multivitamins and cardiovascular risk.
Trial A study in which the subjects are randomly distributed into groups which are either subjected to the experimental procedure (as use of a drug) or which serve as controls In a recent trial, patients randomized to receive Drug X in addition to standard of care showed a significant decrease in recovery time for total knee replacement surgery.
