Mortality and attrition
Could you please advice me on the most convenient way to correctly identify individuals were vital status in unknown?
We are investigating associations between measures of kidney function from the nurse Health assesment and mortality up to wave 7. I have identified individuals reported diseased (with the help of previous advice from the support forum). When interpreting our data we need to understand how to separate the outcome into 1) reported diseased; 2) Alive (regardless if the sunbject participated in a new interview) 3) No Contact/Vital status unknown.
