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
- How was the sample size determined?
- 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
- Were participants randomly
assigned to groups and were
the two groups similar at the
start (before the intervention)? Yes No Not clear - Were the interventions well
defined and consistently
delivered? Yes No Not clear - Were the groups treated
equally other than the
difference in interventions? Yes No Not clear - If no difference was found, was
the sample size large enough
to detect a difference if one existed? Yes No Not clear - 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
