Ratio-eu-lab duomenų tipo profilis apibrėžimai
Guidance on how to interpret the contents of this table can be foundhere
| 0. Ratio | |
| Definition | A measured ratio (or a ratio that can potentially be measured) and uncertainty of the measurement. This profile imposes that the code system for units be UCUM. A relationship of two Quantity values - expressed as a numerator and a denominator. |
| Short | A measured ratio using UCUMA ratio of two Quantity values - a numerator and a denominator |
| Comments | The Ratio datatype should only be used to express a relationship of two numbers if the relationship cannot be suitably expressed using a Quantity and a common unit. Where the denominator value is known to be fixed to "1", Quantity should be used instead of Ratio. |
| Control | 0..* |
| Is Modifier | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present ( (numerator.exists() and denominator.exists()) or (numerator.empty() and denominator.empty() and extension.exists()))ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present ((numerator.exists() and denominator.exists()) or (numerator.empty() and denominator.empty() and extension.exists())) |
| 2. Ratio.extension:uncertainty | |
| Slice Name | uncertainty |
| Definition | The primary measure of variance/uncertainty of the value (the square root of the sum of the squares of the differences between all data points and the mean). |
| Short | Standard Deviation (same units as the quantity) |
| Comments | standardDeviation has the same units as the quantity. It is used to normalize the data for computing the distribution function. Applications that cannot deal with probability distributions can still get an idea about the confidence level by looking at standardDeviation. |
| Control | 0..1 |
| Type | Extension(Uncertainty) (Extension Type: decimal) |
| Is Modifier | false |
| Summary | false |
| Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))ext-1: Must have either extensions or value[x], not both ( extension.exists() != value.exists())ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists()) |
| 4. Ratio.extension:uncertaintyType | |
| Slice Name | uncertaintyType |
| Definition | A code specifying the type of probability distribution for the uncertainty. |
| Short | Probability Distribution Type for uncertainty |
| Comments | This is only meaningful if there is also an uncertainty extension. If there is an uncertainty extension with no type, this means that the probability distribution type is unknown. In that case, the uncertainty has the meaning of an informal guess. |
| Control | 0..1 |
| Type | Extension(Uncertainty type) (Extension Type: code) |

| Short | A measured ratio using UCUM |

If both are absent, there SHALL be some extension present ( (numerator.exists() and denominator.exists()) or (numerator.empty() and denominator.empty() and extension.exists())) |
| 2. Ratio.id | |
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Short | Unique id for inter-element referencing |
| Control | 0..1 This element is affected by the following invariants: ele-1 |
| Type | id |
| Is Modifier | false |
| XML Format | In the XML format, this property is represented as an attribute. |
| Summary | false |
| 4. Ratio.extension | |
| Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Short | Additional content defined by implementations |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |
| Control | 0..* |
