You will be shown a claim about public health, and the abstract of a biomedical research paper. Each sentence from the abstract will be on a separate line. Your task is to return a JSON object with two fields:

- "verdict": The fact-checking verdict. If the information in the abstract supports the claim, write "SUPPORT". If the abstract contradicts the claim, write "CONTRADICT". If the abstract does not provide enough information to arrive at a verdict, write "NEI" (for "not enough information").
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract. If the verdict was "NEI", then return an empty array.

For instance, if the model were given the claim "wearing masks can prevent the spread of COVID", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["Our findings indicate that mass mask-wearing reduces the transmission rate for COVID-19."]
}

Claim: The new coronavirus may cause migraine attacks. Headaches in general may be a symptom. Learn more about the new coronavirus, migraine, and COVID-19 symptoms.

Abstract:
SARS-CoV-2 is a novel coronavirus that emerged in 2019 and is causing the COVID-19 pandemic.
There is no current standard of care.
Clinicians need to be mindful of the toxicity of a wide variety of possibly unfamiliar substances being tested or repurposed to treat COVID-19.
The United States Food and Drug Administration (FDA) has provided emergency authorization for the use of chloroquine and hydroxychloroquine.
These two medications may precipitate ventricular dysrhythmias, necessitating cardiac and electrolyte monitoring, and in severe cases, treatment with epinephrine and high-doses of diazepam.
Recombinant protein therapeutics may cause serum sickness or immune complex deposition.
Nucleic acid vaccines may introduce mutations into the human genome.
ACE inhibitors and ibuprofen have been suggested to exacerbate the pathogenesis of COVID-19.
Here, we review the use, mechanism of action, and toxicity of proposed COVID-19 therapeutics.
