Hi David, until we discovered that a few scores use non Integral values, there was no need for a 'real' type with no units. There is a CR to enable DV_ORDINAL to have real values. Until then, I would suggest using the DV_QUANTITY approach, that's the most frequently used one in the past. Other than these scores, I have never heard of a real value that doesn't have units in medicine. Does anyone know of any? If there is one, we would need a new data type as well, but it still wouldn't be the one to use for scores.
