This calculator is an investigational, beta-stage machine-learning tool developed solely to generate exploratory estimates of in-hospital survival in patients with rodenticide-induced hepatotoxicity treated with plasma exchange.

Data security and confidentiality: We do not save any data entered in this tool.

Intended scope: The model has not been validated for other causes of liver injury or failure, other patient populations, or other treatment approaches. Use outside this defined population is not supported.

Not for clinical decision-making: Outputs are probabilistic estimates for research and informational purposes only. They do not constitute medical advice, diagnosis, treatment guidance, or an individual prognosis and must not be relied upon as the sole or primary basis for any clinical decision, including initiation, escalation, withholding, or withdrawal of treatment.

Validation and accuracy: The model has not undergone independent external or multicentre validation. No representation or warranty is made regarding the accuracy, completeness, reliability, or applicability of any prediction to an individual patient.

Clinical responsibility: All patient-care decisions remain the responsibility of appropriately qualified healthcare professionals exercising independent clinical judgment.

Data handling: No patient-identifiable information should be entered unless expressly required.

Acceptance of limitations: Use of the calculator constitutes acknowledgement of its investigational status and the limitations stated above.
