Rates are per 1,000 persons per year. Burden is calculated as the percentage of HSI encounters compared to the total of all documented injuries and illnesses. Light gold shaded cells indicate a positive linear regression slope for HSI rate over time at α = 0.05. Light blue shaded cells indicate a negative linear regression slope for HSI rate over year at α = 0.05 (hospitalization rates at Fort Bliss and Fort Stewart).
