摘要:Many studies have assessed the volume-outcome relationship in cancer patients, but most focused on better outcomes in higher volume groups rather than identifying a specific threshold that could assist in clinical decision-making for achieving the best outcomes. The current study...

摘要:Two models are mostly used to predict survival in cirrhosis: the Child–Pugh score (CP score) and the model for end-stage liver disease score (MELD score).

摘要:... Both Cox proportional hazards model (Cox) and accelerated failure time model (AFT) have been widely adopted to the high risk and low risk classification or survival time prediction for the patients’ clinical treatment. Nevertheless, two main dilemmas limit the accuracy o...

摘要:... Two Cox proportional hazards models are used to describe the promotion process from non-retired employees and the retirement process, respectively. To account for a potential negative correlation between the two outcomes, promotion and retirement, frailty terms are introduce...

摘要:Abstract(#br)The Cox proportional hazards model is the most used statistical model in the analysis of survival time data. Recently, a random weighting method was proposed to approximate the distribution of the maximum partial likelihood estimate for the regression coefficient in ...

摘要:... The Cox proportional hazards model is one such method that is widely used. As more extensions of the Cox model with time‐dependent covariates are developed, simulations studies will grow in importance as well. An essential starting point for simulation studies of time‐t...
