Which of the following is NOT a term associated with disease classification?

The term "beneficial" does not relate to disease classification in the context of epidemiology or pathology. Typically, terms associated with disease classification help in understanding and categorizing diseases based on their origins, effects, or patterns within populations.

"Iatrogenic" refers to conditions or effects that result from medical treatments or interventions, indicating a source of disease directly linked to healthcare practices. "Incidence" pertains to the rate of new or newly diagnosed cases of a disease within a specific period, providing crucial data for understanding disease impact and epidemiology. "Endemic" describes a disease or condition regularly found and consistently present in a particular geographic area or population.

These terms contribute to a comprehensive understanding of diseases, while "beneficial" does not fit within this framework as it suggests a positive effect rather than classification or categorization of diseases.
