Table 3. Relative hazard of death for statin use after cancer diagnosis vs. no statin use (n = 7813).
Model | HR (95%) | P-value |
---|---|---|
Model 1: Unadjusted model using statin as a non-time-dependent variable | 0.69 (0.66, 0.72) | <0.0001 |
Model 2: Unadjusted model using statin as a time-dependent variable (removes immortal time bias) | 0.76 (0.72, 0.80) | <0.0001 |
Model 3: Model 2 + age, sex, race, neighborhood income adjustment | 0.79 (0.75, 0.83) | <0.0001 |
Model 4: Model 3 + stage, grade, tumor size | 0.80 (0.76, 0.84) | <0.0001 |
Model 5: Model 4 + resection, radiation and chemotherapy | 0.80 (0.76, 0.84) | <0.0001 |
Model 6: Model 5 + obesity, dyslipidemia, diabetes/IGT, chronic pancreatitis and COPD | 0.79 (0.75, 0.93) | <0.0001 |
Model 7: Modeling statin as a time-dependent variable that lags by 2 months (removes reverse causation, restricts population to >2 month survivors) | 0.94 (0.89, 1.01) | 0.08 |
HR = hazard ratio for statin use; IGT = impaired glucose tolerance, COPD = chronic obstructive pulmonary disease
