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: Are hydroxychloroquine and chloroquine safe? Hydroxychloroquine and chloroquine are generally considered safe when taken for conditions that they have been approved for.

Abstract:
Backgrounds.
Since COVID-19 outbreak, various agents have been tested but no proven effective therapies have been identified.
This has led to a lot of controversies among associated researches.
Hence, in order to address the issue of using hydroxychloroquine in treating COVID-19 patients, we conducted a systematic review and meta-analysis.
Methods.
A thorough search was carried out to find relevant studies in MEDLINE, medRxiv, PubMed, Cochrane Database, China Academic Journals Full-text Database and Web of Science.
Two investigators independently reviewed 274 abstracts and 23 articles.
The trials which evaluated hydroxychloroquine for treatment of COVID-19 were included for this systematic review.
Two investigators assessed quality of the studies and data extraction was done by one reviewer and cross checked by the other.
Results.
Five trials involving 677 patients were included while conducting the meta-analysis.
Compared with the control group, hydroxychloroquine with or without azithromycin showed benefits in positive-to-negative conversion of SARS-CoV-2 (odds ratio [OR], 1.95 [95% CI,0.19 to 19.73] and a reduction in progression rate (OR, 0.89 [95% CI, 0.58 to 1.37]), but without demonstrating any statistical significance.
This systematic review has also suggested a possible synergistic effect of the combination therapy which included hydroxychloroquine and azithromycin.
However, the use of hydroxychloroquine alone was associated with increased mortality in COVID-19 patients.
Conclusion.
The use of hydroxychloroquine with or without azithromycin for treatment of COVID-19 patients, seems to be effective.
The combination of hydroxychloroquine and azithromycin has shown synergic effects.
However, mortality rate was increased when the treatment was conducted with hydroxychloroquine.
