From: Transit time flow measurement of coronary bypass grafts before and after protamine administration
Mean graft flows (A) and pulsatility indices (B) pre- and post-protamine: single grafts with pre- and post-protamine TTFM with ACI > 30 (both pre- and post-protamine) and same MAP range (for each graft). Data reported as medians. Boxes represent the 1st to 3rd (IQR) quartile while the whiskers are from the min to the max values and are truncated to no longer than 1.5 times the IQR. ACI = acoustic coupling index; MAP = mean arterial pressure; MGF = mean graft flow; PI = pulsatility index; TTFM = transit-time flowmetry
