Table 2 Coefficients and 95% confidence intervals from the FPM and Poisson models of the mortality rates with two time-scales (t1 as attained age, and t2 as time since MPN diagnosis) for cohort of Swedish MPN patients diagnosed during 1987-2009 and matched comparators. Note: the spline coefficients are not interpretable on their own but they are used for making smooth predictions of the mortality rates
