Examples show that the inclusion of time-dependent covariables defined as step functions into the restricted cubic spline proportional hazards model reduces computation time by a factor of 213 over the Cox model. Advantages of the spline model also include flexibility of the hazard, smooth survival ...

a trend test was performed after the median value of each quartile was entered into the model and treated as a continuous variable. The restricted cubic spline models were with 4 knots (at the 5th, 35th, 65th, and 95th percentiles) were conducted to test whether there was a dose-response ...
(Table2). Inspection of the restricted cubic spline showed that the HR was below unity across the full range of ejection fraction, with the upper 95% CI around the HR crossing unity only at the extreme ends of the range (at around 9% and 70%, respectively), probably due to the small...
The restricted cubic spline as baseline hazard in the proportional hazards model with step function time-dependent covariables. We incorporate a cubic spline function where the tails are linearly constrained, as the baseline hazard, into the proportional hazards model. We show estim... II James,FE...

indicated potential nonlinear relationships between predictors and response variables, following recommendations from Baayen et al. (2006), we addressed this by incorporating restricted cubic splines into our models. These splines, defined by "knots" or change points, allow for the creation of flexible...
MACE was significantly decreased in T3 (adjusted hazard ratio (HR) 0.376, 95% confidence interval (CI) 0.207 to 0.683). The restricted cubic spline curve analysis visualized an inverted S-shaped association between 24 h UPE level and the risk of a six-point MACE, indicating a significantly ...
