Answer to Question 1

ANS: A
The main difference is that in a meta-analysis the researcher uses statistics to show the effect of an intervention on an outcome. In a systematic review no statistics are used to draw conclusions about the evidence. A single random controlled trial (RCT) is not as conclusive as a review of several RCTs on the same question. Control trials without randomization may involve bias in how the study is conducted.

Answer to Question 2

ANS: D
The Agency for Healthcare Research and Quality (AHRQ) includes clinical guidelines and evidence summaries. MEDLINE includes studies in medicine, nursing, dentistry, psychiatry, veterinary medicine, and allied health. EMBASE includes biomedical and pharmaceutical studies. PsycINFO deals with psychology and related health care disciplines.
