Category	Description
Pro-HCQ	We consider that a video contains pro-HCQ content when it reproduces claims that the drugs are a cure or prophylaxis for covid-19, reproduces an interview with someone promoting the drugs, includes stories of people allegedly cured by HCQ, and/or incentivizes people to use the drugs by reverberating protocols from the Brazilian Federal Government or any hospital without mentioning that the drugs do not have efficacy as a treatment for covid-19.
Anti-HCQ	We consider that a video contains anti-HCQ content when it reverberates studies that found no evidence of the efficacy of the drugs for covid-19, reproduces instructions from medical authorities to not use the unproven drugs, includes an interview with someone defending that hydroxychloroquine is an unproven drug for covid-19, and/or clearly mention that despite that some people promote hydroxychloroquine, the drugs do not have efficacy for treating covid-19.
Without a clear position	We consider that a video has no clear position when it does not directly associate the drugs with covid-19, or it does not contain pro-HCQ or anti-HCQ content.
