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

backgroundThe importance of supraclavicular lymph node (SCLN) metastases in esophageal cancer (EC) remains unknown. Few studies have reported on the prognostic impact of SCLN metastases on patients with cervical EC (CEC). This study aimed to investigate whether SCLNs should be considered regional lymph nodes and be dissected in patients with CEC.

methodsThis retrospective study enrolled 835 consecutive patients who underwent radical esophagectomy. Of these patients, 67 underwent radical surgery for CEC. These 67 patients were divided into three groups based on the presence of lymph node metastases with or without metastatic SCLNs or the absence of lymph node metastases.

resultsOf the 67 patients, 23 (34.3%) did not have metastatic lymph nodes (pN-negative group), 27 (40.3%) had metastatic lymph nodes except for metastatic SCLNs (pN-positive group without metastatic SCLN), and 17 (25.4%) had metastatic lymph nodes including metastatic SCLNs (pN-positive group with metastatic SCLNs). The 5-year overall survival rate was 58.4% for the pN-negative group, 46.2% for the pN-positive group without metastatic SCLNs, and 7.8% for the pN-positive group with metastatic SCLNs. The pN-positive group with metastatic SCLNs tended to show residual tumor cells and complications after surgery. The presence of metastatic SCLNs was a significantly poor prognostic factor (p = 0.004). The efficacy index was lowest for the lymph nodes in the supraclavicular region.

conclusionsThe prognosis of the CEC patients with metastatic SCLNs was dismal. Although the cervical esophagus is located adjacent to the SCLNs, the SCLNs may be considered extra-regional lymph nodes in patients with CEC.
