Hazard ratios (HR) with 95% confidence intervals (CI) for all cancer in overweight and obese patients with type 2 diabetes, compared to patients with normal weight, using several models for adjustment with covariates.

Model 1: adjustment for gender and also stratification by quartiles of age in order to avoid violation by age of the proportional hazards assumption at Cox regression analysing all cancer.
Model 2: Diabetes duration and HbA1c added as covariates, except for gender and stratification by age quartiles.
Model 3: Insulin treatment also added as covariate, except for gender, duration, HbA1c, and stratification by age quartiles.
