  "description": "A quantity constructed as the quotient of a numerator quantity divided by a denominator quantity. Common factors in the numerator and denominator are not automatically cancelled out. The data type supports titers (e.g., \"1:128\") and other quantities produced by laboratories that truly represent ratios. Ratios are not simply \"structured numerics\", particularly blood pressure measurements (e.g. \"120/60\") are not ratios. In many cases the should be used instead of the .",
