Comparative analysis of APACHE-II and P-POSSUM scoring systems in predicting postoperative mortality in patients undergoing emergency laparotomy

Figure 1 Box-plots in Pearson correlation coefficient using APACHE-II. APACHE-II: Acute physiology and chronic health evaluation II.

Figure 2 Box-plots in Pearson correlation coefficient using P-POSSUM. P-POSSUM: Physiological and operative severity for the enumeration of mortality and morbidity.
