Notes: Each row for each time period (1982–1996; 1997–2005) is based on a different model, and the annual percentage point change is the coefficient estimate on the trend variable in that model, multiplied by 100. All models include controls for age, sex, and proxy, and SUDAAN is used to adjust for complex survey design.
Percentage of total change accounted for by conditions can sum to more than 100% because conditions are examined independently.
**and *indicates statistical significance at the 0.01 and 0.05 levels, respectively.
