How this service works
Lefere 2025 pFIB-c logistic probability of significant (>=F2) liver fibrosis in pediatric MASLD from sex (boy/girl), hypertension, ALT (U/L), caller-assigned CDC/WHO weight Z-score, HOMA-IR, and caller-assigned Black ethnicity. Table 2 coefficients. Derivation rule-out cutoff 0.226. magent does not assign race or ethnicity and does not compute LMS Z-scores. Not a biopsy, not pFIB-6, and not a diagnosis.
Output
Returns the pFIB-c logistic probability (0–1) of significant (≥F2) liver fibrosis in a pediatric MASLD patient, derived from Lefere 2025 Table 2 coefficients. A result below 0.226 meets the derivation rule-out cutoff. This is a probability estimate only — not a biopsy result, not pFIB-6, and not a clinical diagnosis.
Example use cases
Pediatric MASLD clinic fibrosis triage
“I have a 10-year-old girl with MASLD, no hypertension, ALT of 62 U/L, weight Z-score of 1.8, HOMA-IR of 3.5, and she is not Black — can you run the pFIB-c score to see if she's above the 0.226 rule-out cutoff for significant fibrosis?”
Research cohort fibrosis risk batch assessment
“For our study patient — a boy, hypertension present, ALT 120 U/L, weight Z-score 2.7, HOMA-IR 6.1, Black ethnicity true — what does the Lefere 2025 pFIB-c model give as the probability of F2 or worse liver fibrosis?”
Avoiding biopsy with low-risk score
“My patient is a girl, no hypertension, ALT 45 U/L, weight Z-score 1.2, HOMA-IR 2.0, not Black — compute her pFIB-c probability so I can decide whether she falls below the 0.226 rule-out threshold and might not need a liver biopsy.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/pfib_cWhen to prefer
Use this endpoint when you need the specific Lefere 2025 pFIB-c logistic model for pediatric MASLD fibrosis risk estimation and already have all six inputs pre-computed (ALT in U/L, caller-assigned weight Z-score, HOMA-IR, hypertension status, sex, and Black ethnicity). Prefer this over pFIB-6 or adult fibrosis scores when the patient is a child and the Lefere 2025 Table 2 formulation is required. Do not use if you need LMS Z-score computation, HOMA-IR calculation from raw glucose/insulin, race assignment, or a diagnostic conclusion.
Side effects
- Missing required query parameters (sex, hypertension, alt_u_l, weight_z_score, homa_ir, black_ethnicity) returns a validation error
- ALT outside 5–500 U/L range may return an out-of-range error
- HOMA-IR outside 0–50 range may be rejected
- weight_z_score outside -5 to 8 may be rejected
- Invalid sex value (not 'boy' or 'girl') returns an enum validation error
- Payment not provided or insufficient USDC returns 402 Payment Required
