Effect of ankle versus thigh tourniquets on post-operative pain in foot and ankle surgery

Figure 1 Scatter plots illustrating the correlation (r) between tourniquet time and the immediate post-operative, six-hour, and 24-h pain scores. A: Recovery pain score vs tourniquet time minutes; B: 6 h pain score vs tourniquet time minutes; C: 24 h pain score vs tourniquet time minutes. Note the weak correlation between tourniquet time and immediate post-operative pain scores with the absence of correlation to the six- and 24-h pain scores.
