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
Background: Totally minimally invasive Ivor-Lewis esophagectomy (ILMIE) is a particularly challenging procedure. Despite recent improvements, technical difficulties, mainly in creating intrathoracic anastomosis, still account for a high rate of anastomotic leaks. We present a modified ILMIE technique, with a transhiatal esophageal transection during the laparoscopic stage, aimed at facilitating the thoracoscopic approach and overcoming some of its pitfalls. Methods: Twenty-four consecutive patients with Siewert I and Siewert II esophago-gastric junction tumors with a 8 cm maximum involvement of distal esophagus were included in the study and underwent modified ILMIE with transhiatal esophageal transection and transabdominal (Pfannestiel) specimen extraction. A frozen section examination of specimen margin was obtained while repositioning the patients for thoracoscopic access in prone position. An end-to-side mechanical anastomosis, reinforced by a 3-0 running suture, was performed. Results: There were no major intraoperative complications. Eleven patients (45.8%) had a Clavien-Dindo grade higher than 2 postoperative complication, including one (4.2%) type II anastomotic leak. The mean number of harvested lymph nodes was 31.5 ± 17.2 and we recorded 1 R1 resection (4.2%). Disease free survival rate at 1 year, irrespective of the pathologic stage, was 67%. Conclusions: Modified ILMIE seems to be a safe alternative to the traditional technique. Transabdominal specimen extraction allows a reduced minithoracotomy, a better thoracoscopic workspace and early availability of a frozen section for examination. Larger series are needed to assess possible benefits on postoperative and oncological outcomes.
