Correct Answers
Biomarker ✅Objective indicators of medical state- observed outside patient

Medical sign ✅objective indication of some medical fact or characteristic that may be

Symptoms ✅Patients perceive about themselves

WHO biomarker definition ✅Any measurement reflecting an interaction between a
biological system and a potential hazard which may be chemical physical or biological.

cellular level or a molecular interaction

Examples of biomarkers ✅Salivary cortisol
Body mass index

Blood pressure
Glucose testing

Clinical endpoints ✅variables that reflect how a patient (or study participant) feels,

Are biomarkers or clinical endpoints more relevant to biomedical and clinical research
✅Depends on goals. Improve morbidity and mortality—clinical endpoints are more
relevant than biomarker changes with no clear clinical outcomes but not all clinical
endpoints are made equal

There must be solid scientific evidence indicating that biomarker reliably and
accidentally predicts clinical outcomes....... ✅Positive or negative

Correlation vs. Causation ✅correlation does not equal causation

, Don't mistake causation with correlation. Multiple disease pathways must be involved,
biomarker.... ✅May be indirect sign of pathway that isn't part of disease process

Using biomarkers as surrogate endpoints provide interim information about... ✅Safety
and efficacy of treatment without waiting for poor clinical outcomes

Using biomarkers as surrogate endpoints allows researchers to design.... ✅Smaller
studies which shortens time and expense to run trials

Three possible endpoints of biomarkers of health ✅-better understanding of
physiological processes
-pathology of disease states
-effects of an intervention on these processes

Reliability ✅consistency of measurement

Accuracy ✅how close a measurement is to the true value

BBH ✅Designed to integrate biological behavioral psychological socio-cultural and
environmental approaches to the study of science behind health

Multidisciplinary ✅Working side by side
