1 · What the graph read from it

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.

2 · The registry

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

backgroundIn esophageal cancer, long-term outcomes of minimally invasive surgery using endoscopic surgery are currently being verified. However, most trials have compared thoracic procedures; few studies have focused on the abdominal procedures, which are important for lymph node dissection in radical esophageal cancer surgery. Hand-assisted laparoscopic surgery (HALS) is a simple and minimally invasive procedure. Although HALS superiority in short-term outcomes has been reported, its oncological safety in esophageal cancer remains unclear. Therefore, we retrospectively evaluated oncological safety of HALS compared with that of conventional open laparotomy (OL) in radical surgery for thoracic and abdominal esophageal cancer.

methodsWe retrospectively analyzed the postoperative survival in 142 patients who underwent radical esophageal cancer surgery at our hospital between May 2012 and May 2017, with and without propensity score matching (PSM) between groups.

resultsBefore PSM, OL (n = 65) and HALS (n = 77) groups differed significantly in overall survival (OS) (3-year OS rate: 74.2% and 87.3%, respectively; log-rank p = 0.040). Additionally, clinical abdominal lymph node metastasis (cALNM) independently predicted OS (p = 0.031). After PSM, the OL and HALS groups did not differ significantly in OS (3-year OS rate: 80.5% and 89.8%, respectively; log-rank p = 0.716). There was no statistically significant difference in abdominal-specific recurrence-free survival between the OL and HALS group before and after PSM.

conclusionHALS may be a well-accepted procedure for radical esophagectomy in esophageal cancer, with oncological safety, including local control specific to the abdomen, comparable to that of the conventional OL.
