values are calculated from chi-square tests of the CHHF versus non-CHHF groups. CHHF: cold hypersensitivity in the hands and feet; Non-CHHF: noncold hypersensitivity in the hands and feet. 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?”
