*LRT test is based on log likelihood and is not appropriate for comparing first event model (CoxPH model) and recurrent events models (Cox extension models).
†The resampling procedure was based on the CoxPH model in the BS test and hence the extended models were not fitted for first event only when compared with the CoxPH model.
‡Models are not nested.
