Regression coefficients: full results

In this section, we present the full results for the regression coefficients part of the simulation study. Included are also the results for \(CH_{1}\) (multiple imputation using only the cumulative hazard for REL) and \(Ref\) (model fitted on full dataset prior to any missigness being induced). Results from the imputation methods are those with \(m = 50\).
