CHHF: cold hypersensitivity in the hands and feet; Non-CHHF: noncold hypersensitivity in the hands and feet; OR: odds ratio; CI: confidence interval; Ref: reference. “Non-CHHF” was employed as the reference in every analysis. Sample questions: digestion: “how is your digestion?”; appetite: “how is your appetite?”; symptoms (discomfort in the upper abdomen, vomiting, motion sickness, exhaustion when hungry, belching, epigastric burning, postprandial fullness, nausea, epigastric pain, and bloating): “do you have any of the following symptoms?” Symptoms are the sum of “often” and “sometimes” responses.
