FLIPI24 24-Month Event Probability Calculator (Maurer 2025)
x402
FLIPI24 24-Month Event Probability Calculator (Maurer 2025) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Computes 24-month event probability for newly diagnosed follicular lymphoma using the Maurer 2025 FLIPI24 Cox model (Table S5) from age, hemoglobin, WBC, LDH/ULN ratio, and beta-2 microglobulin, with low/intermediate/high risk strata.

How this service works
Maurer 2025 FLIPI24: 24-month event probability in newly diagnosed follicular lymphoma from age (nonlinear, inflection at 75), hemoglobin, WBC, LDH/ULN, and beta-2 microglobulin. Table S5 Cox algorithm assuming R-CHOP or B-R-like immunochemotherapy and 50% anti-CD20 maintenance. Low/intermediate/high at 0.10 and 0.15. Not Solal-Céligny FLIPI 2004. Not a diagnosis or treatment order. magent does not assay labs.
Output
Returns a 24-month event probability (numeric, 0–1) and a risk stratum classification (low, intermediate, or high) based on the Maurer 2025 Table S5 Cox proportional hazards model, calibrated for patients receiving R-CHOP or bendamustine-rituximab-like immunochemotherapy with ~50% anti-CD20 maintenance. Risk strata use thresholds of 0.10 and 0.15.
Example use cases
Pre-treatment FL risk stratification
“My newly diagnosed follicular lymphoma patient is 72 years old, hemoglobin is 9.8 g/dL, WBC is 10.1 (10^9/L), LDH/ULN ratio is 1.8, and B2M is 4.5 mg/L — run the FLIPI24 model and tell me if they're low, intermediate, or high risk before we start immunochemotherapy.”
Clinical trial enrollment triage
“We need FLIPI24 risk strata for a trial screening: the patient is 58 years old, hemoglobin 13.4 g/dL, WBC 5.2, LDH/ULN 0.9, and beta-2 microglobulin 2.1 mg/L. What's the 24-month event probability and Maurer 2025 risk category?”
High-risk FL patient identification
“Can you flag whether this FL patient is high risk per FLIPI24? They're 80 years old, hemoglobin 8.5 g/dL, WBC 11.5, LDH/ULN ratio 2.6, and B2M is 6.2 mg/L — assuming they'll be treated with R-CHOP plus maintenance.”

Endpoint
GEThttps://api.magentlab.com/api/calc/flipi24When to prefer
Use this endpoint when you need the Maurer 2025 FLIPI24 prognostic score specifically — distinct from the original Solal-Céligny FLIPI 2004 — for newly diagnosed follicular lymphoma patients being considered for R-CHOP or bendamustine-rituximab immunochemotherapy. Prefer this over generic FLIPI calculators when the nonlinear age effect (inflection at 75) and beta-2 microglobulin are clinically relevant and lab values are already known.
Side effects
- Missing required query parameter (age, hemoglobin_g_dl, wbc_10e9_l, ldh_uln_ratio, or b2m_mg_l) returns 400 error
- Age outside 18–120 or numeric values outside valid ranges may be rejected or clamped depending on implementation
- Non-integer age value may cause validation error
- Payment not provided or invalid x402 payment header results in 402 Payment Required
- Server-side error returns 500 with no probability output
