Analysis of the learning curve for artificial pneumothorax during an endoscopic McKeown-type resection of oesophageal carcinoma.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDue to the large trauma caused by conventional open surgery, minimally invasive esophageal cancer surgery has been gradually carried out, and there is no report on the learning curve for artificial pneumothorax during an endoscopic McKeown-type resection of oesophageal carcinoma.
methodsForty cases of McKeown resection of oesophageal carcinoma with artificial pneumothorax that were completed by the same operator between December 2017 and August 2019 were analysed. The patients were divided into four groups (A, B, C, D) of 10 cases each according to the order of operation. The operation time, intraoperative blood loss, total lymph nodes and left recurrent laryngeal nerve lymph nodes resection, conversion rate, complication rate and hospitalization time were compared between the four groups.
resultsThe operation time of the four groups were as follows: A, 243.2±44.1 min; B, 265.0±59.3 min; C, 255.8±41.7 min; D, 201.0±16.2 min, there were significant difference in terms of the operation time between group A, group B, group C and group D (P<0.05). Moreover, groups A and C all differed significantly from group D in the number of dissected left recurrent laryngeal nerve lymph nodes. However, no significant inter-group differences were observed in the number of trans-laparotomy and trans-thoracotomy, number of dissected total lymph nodes, intraoperative blood loss, incidence of postoperative complications and postoperative length of hospital stay (P>0.05).
conclusionsArtificial pneumothorax during an endoscopic McKeown-type resection of oesophageal carcinoma required a learning curve of approximately 30 cases.
