Boxplots demonstrating the effects of lidocaine therapy on duration of POR and total reflux volume. Duration of postoperative reflux (POR) and total reflux volume were compared between horses that were administered lidocaine continuous rate infusion postoperatively (a and b) or intraoperatively (c and d). The box represents the 25th and 75th percentiles of the data, the horizontal line across the middle of the box represents the median and the dot is the mean. Post-op = postoperatively, Intra-op = intraoperatively
