✔✔Positive predictive value - ✔✔Probability the person actually having the disease
when the screening test or diagnostic test is positive
✔✔Negative Predictive Value (NPV) - ✔✔The probability of the person being free of
disease when the screening test or diagnostic test is negative
✔✔Clinically significant - ✔✔Referring to results that have clinical significance
✔✔Natural history of disease - ✔✔Nature of the disease and how it progresses
✔✔primary prevention - ✔✔Interventions aimed at preventing the condition, disorder or
