Synopsis

What was the purpose of the study (research questions, purposes, and hypotheses)?

How was the sample obtained?

What inclusion or exclusion criteria were used?

Who from the sample actually participated or contributed data (demographic or clinical profile and dropout rate)?

What methods were used to collect data (e.g., sequence, timing, types of data, and measures)?

Was an intervention tested?                                             Yes   No

  1. How was the sample size determined?
  2. Were patients randomly assigned to treatment groups?

What are the main findings?

Credibility

Is the study published in a source
that required peer review?                                                Yes   No   Not clear

*Did the data obtained and the
analysis conducted answer the
research question?                                                            Yes   No   Not clear

Were the measuring instruments
reliable and valid?                                                            Yes   No   Not clear

*Were important extraneous
variables and bias controlled?                                          Yes   No   Not clear

*If an intervention was tested,
answer the following five questions:                                Yes   No   Not clear

  1. Were participants randomly
    assigned to groups and were
    the two groups similar at the
    start (before the intervention)?  Yes   No   Not clear
  2. Were the interventions well
    defined and consistently
    delivered?  Yes   No   Not clear
  3. Were the groups treated
    equally other than the
    difference in interventions?                                      Yes   No   Not clear
  4. If no difference was found, was
    the sample size large enough
    to detect a difference if one existed?                      Yes   No   Not clear
  5. If a difference was found, are
    you confident it was due to the
    intervention?  Yes   No   Not clear

Are the findings consistent with
findings from other studies?                                      Yes   Some   No   Not clear

Are the findings credible?                          Yes All   Yes Some   No

Clinical Significance

Note any difference in means, r2s, or measures of clinical effects (ABI, NNT, RR, OR)

*Is the target population clearly
described?                                                                        Yes   No   Not clear

*Is the frequency, association, or
treatment effect impressive enough
for you to be confident that the finding
would make a clinical difference if used
as the basis for care?                                                         Yes   No   Not clear

Are the findings
clinically significant?                                 Yes All   Yes Some   No

* = Important criteria
