Effect and safety of mark-guided vs standard peroral endoscopic myotomy: A retrospective case control study

Figure 2 High-resolution manometry, Eckart score and 36-Item Short-Form Health Survey scores at 3-mo follow-up in the mark-guided peroral endoscopic myotomy group and standard peroral endoscopic myotomy group. A-D: The pre-operative high-resolution manometry and Eckart scores were significantly decreased compared with the postoperative values in the two groups (all P < 0.001); E, F: The pre-operative 36-Item Short-Form Health Survey scores were significantly improved compared with the postoperative values in both groups (all P < 0.001).
