Term
o Methods
Definition
• Study population- what is the population being studied and what are the inclusion and exclusion criteria for the subjects
Term
o Methods
Definition
• Study hypothesis- what is the study question?
Term
o Methods
Definition
• Sample size and statistical power-
• how many subjects?
• Are the number of people enough to show statistical significance?
• Power analysis? ( minimal number of subjects to guarantee usable results)
Term
o Assignment
Definition
• Assignment process: What method is used to identify and assign subjects to study and control groups? ( is it observed or randomization?) how are you assigning subjects?
Term
o Assignment
Definition
• Confounding variable: are there differences in control and experimental group that might affect the outcome of the investigation?
Term
o Assignment
Definition
• Masking ( so that subjects don’t know what grp theyre in): single blind- subjects don’t know what group they are in. Double blind : subjects and experimenter don’t know what group the patients are in
Term
o Assessment
Definition
• Appropriate measurement: does the measurement answer the study question?
Term
o Assessment
Definition
• Accurate and precise measurement: is the measurement an accureate and precise measure of the phenomenon that the investigation is measuring? Is the instrument reliable? Complete and unaffected by observation? Is the follow up of subjects nearly 100%? Deals with attrition
Term
o Assessment
Definition
• is the follow up of subjects complete and is it affects by subjects or investigators knowledge of the study group or control group assignment?
Term
o Results
Definition
• Estimation- how strong are the observations?
Term
o Results
Definition
• Inference- what statistical techniques are used to take into account or control for differences between the study group and control group that may affect the results?
Term
o Results
Definition
• Adjustment- what statistical techniques are used to take into account or control for differences between the study group and control group that may affect the result
Term
o Interpretation:
Definition
• Contributory cause of efficacy: does the factor increase the probability that the disease will happen ( contributing cause) or lower the probability of an undesirable outcome (efficacy)
Term
o Interpretation
Definition
• Harms and interactions: are adverse effects or interactions that affect the results indentified?
Term
o Interpretation
Definition
• Subgroups: are the outcomes seen in subgroups different from the outcomes seen in the overall investigation?
Term
o Extrapolation
Definition
• Similar individuals, groups, or populations: do the investigators extrapolate the findings from the experiment to that of groups similar to the groups in the experiment?
Term
o Extrapolation
Definition
• Beyond the data: do the investigators extrapolate by spreading the conditions beyond the dose, duration, or other characteristics of the investigation?
Term
o Extrapolation
Definition
• To other populations: do investigators extrapolate to different groups than groups in the experiment
