1. What were the objectives and hypothesis of the study?

This paper examines the article "Patient Perception of Obstetrician-gynecologists' Practices Related to HIV Testing" Victoria et al (2009). The main objectives of this study were as follows (1) determine the percentage of obstetrician-gynecologists' patients who have been tested for HIV (2) examine patient attitudes about HIV testing and patients' knowledge about their own risk status (3) determine primary reasons patients decline to HIV testing and (4) learn patient recall of how their obstetrician-gynecologists approach the topic of HIV testing (Victoria et al 2009).
