Relationship type | First argument type | Second argument type | Description | Example |
---|---|---|---|---|
has_target | Investigation, Intervention | Locus | Relates an intervention or an invetigation to the bodily locus at which it is targetted. | There are several has_target relationships in example 1. lymph node is the target of the investigation biopsy, and groin is the target of the intervention dissection. |
has_finding | Investigation | Condition, Result | Relates a condition to an investigation that demonstrated its presence, or a result to the investigation that produced that result. | In example 1, melanoma is a finding of the biopsy. normal is a finding of PET scan |
has_indication | Drug or device, Intervention, Investigation | Condition | Relates a condition to a drug, intervention, or investigation that is targetted at that condition | In example 3, co-codamol is indicated by pain (which has two mentions, "pain" and "this". |
has_location | Condition | Locus | Relationship between a condition and a locus: describes the bodily location of a specific condition. has_location may also describe the location of malignant disease in lymph nodes, relating an involvement to a locus. | There are three has_location relationships in example 1, melanoma is located in groin, and a second melanoma entity is located in second toe. The involvement "5 out of 10" is located in the lymph node entity. In example 3, pain is located in face. |
Modifies | Negation signal | Condition | Relates a condition to its negation or uncertainty about it | "no evidence" in example 4 is a negation of "secondaries" |
Modifies | Laterality signal | Locus, Intervention | Relates a bodily locus or intervention to its sidedness: right, left, bilateral. | In example 2 there are several laterality modifiers. For instance, the second toe has a laterality of right. For an example of an intervention laterality modifier, consider "right thoracotomy" |
Modifies | Sub-location signal | Locus | Relates a bodily locus to other information about the location: upper, lower, extra- etc. | In example 4 there is a sub-location modifier. The pelvis has a sub-location of extra (as in external to). |
