Summary of the model for the probability of being censored. Estimates are averaged over 25 imputations and standard errors are corrected for the correlation between individuals in the censorship model and for the multiple imputations. Reference categories for categorical variables are given in parentheses. Also included in the model was a spline on time in months.
