This is a chart differentiating the medical condition/injuries, diagnostic tests, diagnosis/injuries and treatment performed prior to date of loss and postdate of loss. When there are multiple accidents, the comparative charts are helpful in isolating injuries to a particular accident. In this case, a comparative chart was prepared to showcase the aggravation of her pre-existing medical conditions comparing it with the new injuries she sustained as a result of the MVA.

The significant details before and after the collision were presented in a tabular format for easy comprehension and for cross-reference. This chart included the list of related diagnoses, diagnostic studies, functional level of the claimant and the treatment which she received before and after the injury.
