Three common diagnoses.

The following three examples illustrate how the same neutral causation method can produce different conclusions when applied to different diagnoses, exposures, and bodies of evidence. That is not a weakness of the method; it is the purpose of the method. A scientifically structured analysis should not predictably favor relatedness, non-relatedness, or apportionment. Instead, it should follow the evidence wherever it leads — sometimes supporting work-relatedness, sometimes failing to support it, and sometimes leaving the question unresolved. These examples demonstrate how the same framework can be applied consistently while producing different, evidence-dependent conclusions.

Same neutral method, three different conclusions. That contrast is the point. The method is neutral because it is applied the same way in each case — not because it produces the same result.

These examples are provided for general educational and illustrative purposes only. They are not intended to describe, evaluate, or determine causation in any specific individual case. Any case-specific causation analysis must be based on the particular diagnosis, exposure history, medical record, scientific literature, and applicable legal or administrative standard.
