Proportional hazards model of variables related to complete response following induction BCG and overall survival

Variable Hazard ratio (95% CI) P-value
Unadjusted Model
 Complete Response 0.60 (0.44, 0.81) 0.0008
Adjusted Model
 Complete Response 0.63 (0.46, 0.86) 0.003
 Age5 1.27 (1.16, 1.40) <0.0001
 Male 1.32 (0.84, 2.08) 0.23
 Papillary 0.65 (0.45, 0.93) 0.02
 Prior chemotherapy 0.95 (0.70, 1.30) 0.76

At risk = 341 and deaths = 167

Age5 = age divided by 5. Example: The hazard ratio refers to the risk of death for a 65-year old relative to a 60-year old, thus there is a 32% increased risk of death as age increases 5 years.
