Using multi-year national survey cohorts for period estimates: an application of weighted discrete Poisson regression for assessing annual national mortality in US adults with and without diabetes, 2000–2006

Table 2 All-cause mortality rates of US adults aged 20 to 84 years (per 1,000 person-years and 95% CI) by calendar year using discretized survival time, NVSS and NHIS follow-up

^aAll-cause mortality from the NVSS was calculated as the number of the US all-cause deaths divided by the total US adults
^bAll-cause mortality from the NHIS was calculated as the weighted number of deaths divided by the total weighted person-years
