ttd.all, ttd.da, and ttd.eular are lists of lists containing parameters
from statistical models of time to treatment discontinuation. ttd.all contains
parameters representative of all patients, ttd.da contains covariates for disease
activity level (moderate, high), and ttd.eular is stratified by EULAR response
(moderate, good).
