Population-Based Analysis of Incidence Rates of Cancer and Noncancer Chronic Diseases in the US Elderly Using NLTCS/Medicare-Linked Database

Table 3

Estimates of 𝑡-statistics for 5-year time trend and male/female differences in the age-adjusted incidence rates of geriatric diseases. Absolute value of 𝑡-statistics larger than 2 approximately corresponds to significant differences with 𝑃<0.05.
