“…This finding was confirmed by other studies indicating more frequent gastrointestinal complaints in NCCP patients such as sore throat, dysphagia, and regurgitation [12,18]. However, patients with NCCP are not generally different to patients with cardiac chest pain (CCP) with regard to demography and long-term follow-up [8,12,23,24]. Risk factors for NCCP are overweight (odds ratio (OR) 3.0, 95% confidence interval (CI) 1.64-5.50), reflux (OR 2.8, 95% CI 1.73-4.32), smoking (OR 2.0, 95% CI 1.27-3.18), aspirin (OR 1.5, 95% CI 1.00-2.31), non-steroidal anti-inflammatory drugs (OR 2.0, 95% CI 1.27-3.16), neuroticism (OR 1.14, 95% CI 1.08-1.21), and anxiety (OR 1.12, 95% CI 1.08-1.17) [24][25][26].…”
