Table 3.

Proportional hazards model for risk of disease worsening event following treatment with BCG: (At risk=434 with no missing data; events=232)

Group 1 – Complete responders (CR) and age < 67 (n = 137)

Group 2 – Complete responders and age ≥ 67, or No CR and age < 62 (n = 198)

Group 3 – No CR, age ≥ 62 and no prior chemotherapy (n = 44)

Group 4 – No CR, age ≥ 62 and prior chemotherapy (n = 55)

Variable Hazard ratio (95% CI) P-value
Group 1 1.00 (reference group) ---
Group 2 1.96 (1.39, 2.77) 0.0001
Group 3 3.08 (1.95, 4.86) <0.0001
Group 4 5.09 (3.37, 7.68) <0.0001

At risk = 434 and events = 232
