| Type | dateTime|Period | 
| [x] Note | See Choice of Data Types for further information about how to use [x] |

| Definition | Describes the expected outcome for the subject. | 
| Control | 0..* | 
| Comments | Multiple repetitions can be used to identify the same type of outcome in different timeframes as well as different types of outcomes. | 
| Invariants | Defined on this element ras-2: Must be <= 100 (expression  : probability is decimal implies probability.as(decimal) <= 100, xpath: not(f:probabilityDecimal) or f:probabilityDecimal/@value <= 100) |

| [x] Note | See Choice of Data Types for further information about how to use [x] | 
| Comments | If range is used, it represents the lower and upper bounds of certainty; e.g. 40-60% Decimal values are expressed as percentages as well (max = 100). | 
| Invariants | Defined on this element ras-1: low and high must be percentages, if present (expression  : (low.empty() or ((low.code = '%') and (low.system = %ucum))) and (high.empty() or ((high.code = '%') and (high.system = %ucum))), xpath: (not(f:low) or f:low[f:code/@value='%' and f:system/@value='http://unitsofmeasure.org']) and (not(f:high) or f:high[f:code/@value='%' and f:system/@value='http://unitsofmeasure.org'])) | 
| RiskAssessment.prediction.relativeRisk | |
| Definition | Indicates the risk for this particular subject (with their specific characteristics) divided by the risk of the population in general. (Numbers greater than 1 = higher risk than the population, numbers less than 1 = lower risk.). | 
| Control | 0..1 |
