Levels of 3-year COCI by patient characteristics.

ObjectiveTo demonstrate that when investigating the relevance of continuity of care for patient outcomes, different definitions can lead to contradicting results.MethodsWe used...

Since 61.9% of patients had a primary COCI equal to 1, we contrasted a primary COCI equal to 1 with a COCI smaller or greater than the median of COCI-values different from 1,...

Univariate and multivariate Cox proportional hazard models for survival analysis among propensity-score-matched patients.

The first column gives the crude hazard ratios (HRs) for the different predictors estimated in univariable Cox regression. The second and third column present the adjusted HRs...
