3. Fig. 2
Forest plot of the association between use of pioglitazone and risk of bladder cancer. Red squares and horizontal lines represent study-specific estimates and 95% CI. The size of the square is proportional to the weights of the individual studies. Black diamond represents pooled estimates (center) and 95% CI (width). Abbreviation: SE: standard error, IV: inverse variance, BC: bladder cancer.
