How this service works
Terrapon 2021 Therapy-Disability-Neurology (TDN) grade. Caller assigns therapy t1-t5, modified Rankin 0-6 (6 is death), and new neurologic deficit. Overall grade is max(T, D, N); t5 or mRS 6 is always 5. D maps mRS 0-1→1, 2-3→2, 4→3, 5→4, 6→5; new deficit is N=2 else N=1. Not a diagnosis and not Clavien-Dindo alone. magent does not grade the event.
Output
Returns the overall TDN grade as an integer from 1 to 5, computed as the maximum of the three sub-dimensions T (therapy), D (disability mapped from mRS), and N (neurologic deficit). Special rules ensure t5 or mRS 6 always yields grade 5.
Example use cases
Postoperative complication grading in neurosurgery
“Grade a complication after a craniotomy — the patient required ICU management (t4), has a new neurologic deficit, and their modified Rankin is now 4. What's their Terrapon TDN grade?”
Benchmarking complication severity across a case series
“I have a patient whose adverse event was managed with an invasive radiologic procedure (t3), their mRS is 2, and there's no new neurologic deficit — what TDN grade does that give?”
Mortality-level event classification
“The patient died — modified Rankin is 6, therapy was t5. What is the Terrapon 2021 TDN grade?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/tdn_gradeWhen to prefer
Use this endpoint when you need to standardize adverse event severity using the Terrapon 2021 TDN classification specifically — particularly for neurosurgical or neurologic procedural outcomes where the three-dimensional therapy/disability/neurology grading is required. Prefer over Clavien-Dindo when neurologic disability and new deficits must be captured separately.
Side effects
- Missing required query parameters (therapy, disability_mrs, or new_neurologic_deficit) returns a 4xx error
- Invalid therapy enum value (not t1–t5) returns validation error
- disability_mrs outside integer range 0–6 returns validation error
- Network or upstream service unavailability returns 5xx
- Payment not provided or insufficient returns 402
