Notes:
• 4% of patients were categorized as “other” and are not represented in this table.
• Overall effect of time was significant using multinomial logistic regression.
• Average yearly change calculated by pairwise logistic regression (target diagnosis vs all others).
• Statistical significance analyzed using χ2 or t-tests, as appropriate.
