FLI (Fatty Liver Index) 계산기

FLI는 0~100 사이의 점수로, 지방간(Hepatic steatosis)을 예측하는 데 사용합니다.
FLI = (e^(0.953×ln(triglycerides) + 0.139×BMI + 0.718×ln(GGT) + 0.053×waist – 15.745)) / (1 + e^(0.953×ln(triglycerides) + 0.139×BMI + 0.718×ln(GGT) + 0.053×waist – 15.745)) × 100

FLI ＜ 30 : rule out hepatic steatosis (SN = 87%, LR- = 0.2)
FLI ≥ 60 : rule in hepatic steatosis (SP = 86%, LR+ = 4.3)
SN = Sensitivity / SP = Specificity
LR+ = Positive likelihood ratio
LR- = Negative likelihood ratio
