2. Figure 1
Morbidity after cholecystectomy. Complications occurred in 11 of 33 (33%) patients with cirrhosis but only 5 of 31 (16.1%) patients without cirrhosis after cholecystectomy. Repeat surgeries and hospitalizations as a result of the index surgery were assessed over a 90-day period. The proportion depicting anemia reflects those patients requiring blood transfusions, whereas the proportion depicting coagulopathy represents patients requiring plasma transfusions. The percentage of patients with each outcome is shown; some patients had more than one outcome.

3. Figure 2
The use of preoperative scores in predicting postoperative outcomes after cholecystectomy. Morbidity was determined by predetermined criteria over a 90-day period as defined in the Materials and Methods section. The use of the preoperative score in predicting postoperative morbidity and mortality was assessed by determining the area under the curve of a receiver operator characteristic curve.

Comparison of preoperative scores and postoperative complications. Scatter plots of preoperative MELD scores (top panel) or Child-Pugh scores (bottom panel) for persons with or without postoperative complications after cholecystectomy. Complications included death or morbidity, as defined in the Materials and Methods section, over a 90-day period after surgery.
