Figure 4
Figure 4 Forest plot of mean body-mass index in the non-severe and severe patient subgroups. Filled circles represent the mean difference derived from the studies analyzed. Horizontal bars represent 95%CI. Empty rhombuses show the overall, combined mean difference (point estimation is the middle of the rhombus and CIs are the edges). CI: Confidence interval.

Figure 5 Forest plot of severe acute pancreatitis in the body-mass index < 25 and body-mass index > 25 subgroups. Filled circles represent the odds ratio derived from the studies analyzed. Horizontal bars represent 95%CI. Empty rhombuses show the overall, combined effect (OR is the middle of the rhombus and CIs are the edges). BMI: Body-mass index; CI: Confidence interval; OR: Odds ratio.

Figure 6 Forest plot of severe acute pancreatitis in the body-mass index < 30 and body-mass index > 30 subgroups. Filled circles represent the odds ratio derived from the studies analyzed. Horizontal bars represent 95%CI. Empty rhombuses show the overall, combined effect (OR is the middle of the rhombus and CIs are the edges). BMI: Body-mass index; CI: Confidence interval; OR: Odds ratio.

Figure 7 Forest plot of acute pancreatitis severity comparing the normal body-mass index group (body-mass index 18. 5-25) to other body-mass index categories. Filled circles represent the odds ratio derived from the studies analyzed. Horizontal bars represent 95% CI. Empty rhombuses show the overall, combined effect (OR is the middle of the rhombus and CIs are the edges). BMI: Body-mass index; CI: Confidence interval; OR: Odds ratio.

Figure 8 Subgroup analysis of body-mass index and acute pancreatitis severity displayed on forest plot. Filled circles represent the odds ratio derived from the studies analyzed. Horizontal bars represent 95%CI. Empty rhombuses show the overall, combined effect (OR is the middle of the rhombus and CIs are the edges). CI: Confidence interval.

Figure 9 Forest plot of mortality comparing the body-mass index < 25 and body-mass index > 25 subgroups. Filled circles represent the odds ratio derived from the studies analyzed. Horizontal bars represent 95% CI. Empty rhombuses show the overall, combined effect (OR is the middle of the rhombus and CIs are the edges). BMI: Body-mass index; CI: Confidence interval; OR: Odds ratio.

Horizontal bars represent 95%CI. Empty rhombuses show the overall, combined effect (OR is the middle of the rhombus and CIs are the edges). BMI: Body-mass index; CI: Confidence interval; OR: Odds ratio.
