| Summary: | Evidence is crucial in strategic
planning for HIV response as well as the monitoring of
results. This paper presents a simple tool that can be used
to analyze the methodological quality of HIV data, its scope
and limitations, and whether it can be accurately compared
with other evidence. The tool, utilized as a questionnaire
or checklist, first identifies the type of document
containing the data; the status and means of its
publication; the epidemiological design used; and the
priority population. Next, the document is analyzed against
a verification list based on eight methodological criteria:
1) objective; 2) inclusion and exclusion criteria; 3) sample
size; 4) sampling technique; 5) error-reduction strategies;
6) data analysis technique; 7) limitations; and 8)
confidence intervals and/or statistical significance. The
paper also presents the results of implementing the tool in
three Latin American countries. |
