what is detection bias?
what is assesor bias?
what is performance bias?
What is the Hawthore Effect?
What is a funnel plot?
Define INCIDENCE, PREVALENCE,RELATIVE RISK AND ODDS RATIO
Incidence and Prevalence Pool Analogy
What is the definition of INCIDENCE?
What is the definition of Prevalence?
Odds Ratio vs Relative Risk
Can Relative risk be significant if CI crosses zero?
NO.
How do ou differentiate between categorical and continous measurements?
write the flowchart for statistical analysis based on study design
what statisical analysis to use for categorical data for two or more small groups?
what are the four variables for diagnostic performance?
Positive predictive value
Negative predictive value
sensitivity
Specificity
Complete the table for Diagnostic Performance Measures:
specificitity
sensitivity
Positive Predictive Value
Negative Predictive Value
ie. SLAP tears on MRI
Define Sensitivity:
ability to detect disease;
ability to detect true positives
Define Specificity:
Ability to detect health:
ability to detect true Negatives
Define Positive Predictive Value:
Probability that the person has the disease given a positive test result
Proportion of positive tests that are TRUE POSITIVES
Define Negative Predictive Value
Probabiity that a person is healthy given a negative test result
Proportion of negative tests that are true negatives
How do Type I and Type II errors relate to false positives and false negatives?
