Hashimoto\u2019s, Type 1 Diabetes Mellitus (T1DM), Fibromyalgia and cannabinoid use with cyclic vomiting syndrome were negatively correlated with AHP, while psychiatric disorders and obstetrics and gynecology (OBGYN) disorders were positively correlated with AHP. The highest rate of diagnosis resulted from a combination of genetic and biochemical testing.
