You will be shown a scientific claim, 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 "smoking causes cancer", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["The results of our meta-analysis provide overwhelming support that cigarette smoking is a risk cause for lung cancer."]
}

Your response should not include any text other than the json.

Claim: Bariatric surgery leads to negative outcomes in mental health.

Abstract:
IMPORTANCE Bariatric surgery is associated with sustained weight loss and improved physical health status for severely obese individuals.
Mental health conditions may be common among patients seeking bariatric surgery; however, the prevalence of these conditions and whether they are associated with postoperative outcomes remains unknown.
OBJECTIVE To determine the prevalence of mental health conditions among bariatric surgery candidates and recipients, to evaluate the association between preoperative mental health conditions and health outcomes following bariatric surgery, and to evaluate the association between surgery and the clinical course of mental health conditions.
DATA SOURCES We searched PubMed, MEDLINE on OVID, and PsycINFO for studies published between January 1988 and November 2015.
Study quality was assessed using an adapted tool for risk of bias; quality of evidence was rated based on GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria.
FINDINGS We identified 68 publications meeting inclusion criteria: 59 reporting the prevalence of preoperative mental health conditions (65,363 patients) and 27 reporting associations between preoperative mental health conditions and postoperative outcomes (50,182 patients).
Among patients seeking and undergoing bariatric surgery, the most common mental health conditions, based on random-effects estimates of prevalence, were depression (19% [95% CI, 14%-25%]) and binge eating disorder (17% [95% CI, 13%-21%]).
There was conflicting evidence regarding the association between preoperative mental health conditions and postoperative weight loss.
Neither depression nor binge eating disorder was consistently associated with differences in weight outcomes.
Bariatric surgery was, however, consistently associated with postoperative decreases in the prevalence of depression (7 studies; 8%-74% decrease) and the severity of depressive symptoms (6 studies; 40%-70% decrease).
CONCLUSIONS AND RELEVANCE Mental health conditions are common among bariatric surgery patients-in particular, depression and binge eating disorder.
There is inconsistent evidence regarding the association between preoperative mental health conditions and postoperative weight loss.
Moderate-quality evidence supports an association between bariatric surgery and lower rates of depression postoperatively.
