A systematic review included 12 studies. The following positive findings were helpful for the diagnosis of arterial disease: abnormal pedal pulses (ankle-arm index <0.5 to 0.9, LR+ = 3.0 to 44.6, LR- = 0.1 to 0.4, sensitivity 0.63 to 0.95, specificity 0.73 to 0.99. Femoral arterial bruit (AAI <0.8 to 0.9, LR+ = 4.7 to 5.7, LR- = 0.7 to -0.8, sensitivity 0.20 to 0.29, specificity 0.95 to 0.96. Venous filling time and colour abnormality had also some predictive power.
