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

backgroundImmune checkpoint inhibitors have been tried for several thoracic malignancies; however, their application as a neoadjuvant therapy in esophageal squamous cell carcinoma (ESCC) has not been studied. We evaluated the feasibility and safety of esophagectomy and total lymphadenectomy after neoadjuvant chemoradiation therapy with pembrolizumab.

methodsBetween 2017 and 2018, 38 patients who received the neoadjuvant therapy followed by radical esophagectomy and total lymphadenectomy for ESCC were analyzed. Twenty-two patients received conventional neoadjuvant chemoradiation therapy (Group 1), and sixteen patients received neoadjuvant chemoradiation therapy with pembrolizumab in clinical trial (Group 2). Two groups were compared retrospectively.

resultsThe basic characteristics of age, clinical stage, location and methods of operation were not different between the two groups. The pathologic stages were higher in Group 2, but the difference was not statistically significant. The operative outcomes, i.e., operation time, blood loss, and numbers of dissected lymph nodes in the thorax, neck, and abdomen were comparable. Complications, including pulmonary complications and anastomotic leakage, were also comparable. The rate of recurrent laryngeal nerve palsy was also comparable between the two groups (31.8%

conclusionsRadical esophagectomy for esophageal squamous cell carcinoma after neoadjuvant chemoradiation therapy with pembrolizumab may not increase the operative risk or reduce the quality of radical dissection including lymphadenectomy. The risk of ARDS after neoadjuvant neoadjuvant chemoradiation therapy with pembrolizumab has to be studied in the further analysis.
