16
Q

Meta-analysis

A

Systematic review using quantitative methods to summarize results, such as by pooling data to determine influence on statistical power

17
Q

Systematic review

A

Study composed of systematic searches to appraise and summarize all medical literature on a specific topic (narrative or qualitative review)

18
Q

Randomized controlled trials

A

Randomized groups: experimental and control. Followed for variables and outcomes of interest. Rigorous study design.

19
Q

Cohort study

A

Non-randomized groups: one with variable of interest, one without. Follow groups to measure outcome.

20
Q

Case-controlled study

A

Patients with outcome of interest and control patients with same outcome; identify exposure

21
Q

Case series / case reports

A

Uncontrolled studies; outcome measure often not reported; possible confounding factors

22
Q

Editorial / expert opinion

A

Purely anecdotal evidence

23
Q

Non empirical evidence x3

A

Clinical experience,
‘n of one’ evidence gathered from patients,
Theory (non-research based)

Often lead to research; bottom of hierarchy

24
Q

Finding good evidence: research question

A

Develop a good research question with PICO: population, intervention, control, outcome measures

25
Q

Finding good evidence: Boolean operators

A

And = results containing both categories
Or = results containing both categories and results for each category alone
Not = one category is completely excluded from results

26
Q

3 conclusions of article critical appraisal

A

1 discard completely (flawed)
2 interpret with caution (questionable)
3 assimilate into practice (trustworthy)

27
Q

5 questions for article critical appraisal

A
1 originality
2 who
3 study design
4 bias
5 size, follow-up
28
Q

Reliability of findings

A

CONSISTENCY

extent to which outcomes are consistent when method repeated; quality of research

29
Q

Validity of findings

A

ACCURACY

the extent to which the instruments or methods used are measuring what they are intended to measure; quality of research

30
Q

2 ways to consider quality of research

A

reliability + validity

31
Q

3 common bias types in clinical research

A

confounding variables
selection bias
measurement bias

32
Q

confounding variable

A

factor that influences the intervention and/or control group causing a suspicious association; influences outcome

33
Q

measurement bias

A

instrument or calibration is not rigorously controlled

34
Q

tool for BIAS risk assessment

35
Q
