  Figure 2. Forest plot of the association between using of alprostadil and the incidence of CIN, the horizontal lines correspond to the study-specific OR and 95% CI, respectively. The area of the squares reflects the study-specific weight. The diamond represents the pooled results of OR and 95% CI.

  Figure 3. Forest plot of the association between using of alprostadil and the Scr level 24 hours after the contrast was administered, the horizontal lines correspond to the study-specific SMD and 95% CI, respectively. The area of the squares reflects the study-specific weight. The diamond represents the pooled results of SMD and 95% CI.

  Figure 4. Forest plot of the association between using of alprostadil and the BUN level 48 hours after the contrast was administered, the horizontal lines correspond to the study-specific SMD and 95% CI, respectively. The area of the squares reflects the study-specific weight. The diamond represents the pooled results of SMD and 95% CI.

  Figure 5. Forest plot of the association between using of alprostadil and the CysC level 48 hours after the contrast was administered, the horizontal lines correspond to the study-specific SMD and 95% CI, respectively. The area of the squares reflects the study-specific weight. The diamond represents the pooled results of SMD and 95% CI.
