Table 2 Proportion of simulations (out of 1000) with P-values < 0.05 for one continuous variable and one binary variable

From: Testing the proportional hazards assumption in case-cohort analysis

Proportionality Variable Corr with time Corr with rank Corr with KM estimate
Proportionality for both variables Continuous 0.059 0.056 0.056
Binary 0.042 0.043 0.045
Proportionality for the continuous but not the binary variable Continuous 0.047 0.048 0.045
Binary 0.646 0.641 0.647
Proportionality for the binary but not the continuous variable Continuous 0.979 0.971 0.967
Binary 0.043 0.045 0.045
Non-proportionality for both variables Continuous 0.994 0.991 0.989
  Binary 0.597 0.586 0.580
