Intracystic glucose is superior to carcinoembryonic antigen in diagnosing mucinous pancreatic cysts in genomic era: Systematic review and meta-analysis

Figure 3 Forest plots showing pooled diagnostic performance of carcinoembryonic antigen. A: Accuracy, with pooled estimate (diamond) 0.72 (95%CI: 0.69-0.76, I² = 44.53%); B: Sensitivity, with pooled estimate 057 (95%CI: 0.52-0.63, I² = 57.43%); C: Specificity, with pooled estimate 097 (95%CI: 0.95-0.99, I² = 79.73%); D: Summary receiver operating characteristic curve for carcinoembryonic antigen in the diagnosis of mucinous pancreatic cysts. Results showed in the legend are supported by the distribution of the plots, and the confidence region was narrow, but the prediction region was broader along the sensitivity axis, suggesting variability in diagnostic performance across studies. CEA: Carcinoembryonic antigen; CI: Confidence interval.
