How this service works
VanWagner 2017 CAR-OLT integer points (Table 3) for 1-year CVD complication after first orthotopic liver transplant: age bands, sex, caller-assigned race (white 7, black 10, other 0), work, education, atrial fibrillation 25, ventilator 13, pulmonary hypertension 9, no HCC 6, hypertension 4, diabetes 4, heart failure 7. Table 4 predicted percent. Not a listing decision. magent does not assign race.
Output
Returns the VanWagner 2017 CAR-OLT integer point total (summed from demographic and clinical variable point values per Table 3) and the corresponding predicted percent probability of a cardiovascular complication within 1 year of first orthotopic liver transplant (from Table 4). This is a prognostic estimate, not a listing decision tool.
Example use cases
Pre-transplant CVD risk stratification
“I have a 62-year-old black male liver transplant candidate with no HCC, a history of hypertension and diabetes, no atrial fibrillation, no ventilator use, no pulmonary hypertension, no heart failure, college educated, and currently working for income — what does the VanWagner CAR-OLT model predict for his 1-year cardiovascular complication risk?”
Comparing risk across two OLT patients
“Can you run the CAR-OLT cardiovascular risk score for two patients? First: a 47-year-old white female, HCC present, atrial fibrillation, no ventilator, no pulmonary hypertension, no hypertension, no diabetes, no heart failure, college education, working. Second: a 66-year-old other-race male, no HCC, no atrial fibrillation, on ventilator, pulmonary hypertension, hypertension, diabetes, heart failure, high school education, not working.”
Documenting post-transplant CVD risk in chart
“For a 55-year-old other-race female liver transplant recipient with no HCC, no atrial fibrillation, not on ventilator, no pulmonary hypertension, hypertension, no diabetes, no heart failure, high school education, not working for income — give me her VanWagner 2017 CAR-OLT point total and the corresponding predicted 1-year CVD complication percentage from Table 4.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/car_oltWhen to prefer
Use this endpoint when you need a deterministic, published-literature-backed integer point score for 1-year cardiovascular complication risk after first orthotopic liver transplant, following the exact VanWagner 2017 methodology. Prefer this over generic CVD risk calculators (e.g. Framingham) when the patient context is specifically post-OLT. This endpoint is appropriate when all 12 required clinical variables are available and a reproducible, citable score is needed for clinical documentation or research.
Side effects
- Missing required query parameter returns an error (all 12 clinical/demographic fields are required)
- Age outside 18-120 integer range returns a validation error
- Invalid enum value for sex, race_group, or education returns an error
- Non-boolean values for clinical flag fields return a parsing error
- Network or payment failure (402 x402 payment required or unpaid)
