Paper 5621-2016 Restricted Cubic Spline Regression: A Brief Introduction Ruth Croxford, Institute for Clinical Evaluative Sciences ABSTRACT Sometimes, the relationship between an outcome (dependent) variable and the explanatory (independent) variable(s) is not linear. Restricted cubic splines are a way ...
Restricted cubic splines are just a transformation of an independent variable.Thus, they can be used not only in ordinary least squares regression, but also in logistic regression,survival analysis, and so on. The range of values of the independent variable is split up, with "knots"defining ...

3). Pathologic type, FIGO stage, tumour size and surgery were included in the final regression models. According to the multivariate Cox regression analysis results of OS, the grade did not meet the qualification of p < 0.01, but as a recognized prognostic factor, it was also ...
Restricted cubic spline models Figure 1 shows the multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the Cox regression models with RCSs for all-cause death and MACE for each drug group. The corresponding HRs and 95% CIs for various PDC values are shown in Sup...

Restricted cubic spline (RCS) and Cox proportional hazards regression models were used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of association between waist circumference and the risk of PLC in males. Results: During a median of 8.9 years of follow-up, 346 PLC ...
