Artificial intelligence based real-time microcirculation analysis system for laparoscopic colorectal surgery

Figure 6 Comparison on the receiver operating characteristic curves of artificial intelligence-based methods and conventional parameters determines the anastomotic complication risk by hypoperfusion. Artificial intelligence (AI) represents the AI-based method. T_1/2max is the time it takes for the indocyanine green fluorescence intensity change to become F_max/2. Rising slope represents F_max/T_max. Time ratio represents T_1/2max/T_max. Area under the curve stands for area under the curve. Statistically significant expresses as P value of less than 0.05. TR: Time ratio; RS: Rising slope; AI: Artificial intelligence; SE: Standard error; CI: Confidence interval; AUC: Area under the curve.
