Which of the following would be the worst source of scientific information when considering if you should take the drug hydroxychloroquine to prevent COVID-19?

the web site for the Centers for Disease Control (cdc.gov) that provides information about the use of hydroxychloroquine
an elected public official who stated that some people had great success using hydroxychloroquine and that it should therefore be prescribed as a preventative
a meta-analysis published in the Annals of Internal Medicine reviewing 24 studies that indicated conflicting evidence on the benefits and harms of using hydroxychloroquine
a study published in the New England Journal of Medicine that showed hydroxychloroquine did not prevent infection in exposed subjects

An elected public official who stated that some people had great success using hydroxychloroquine and that it should therefore be prescribed as a preventative would be the worst source of scientific information when considering whether or not to take the drug. Political figures are not experts in medical or scientific research, and their statements may not be based on solid evidence or data. It is important to rely on information from reputable sources such as the CDC, medical journals, and meta-analyses for accurate and reliable information on medication effectiveness and safety.
