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

backgroundAdenocarcinoma of the oesophagogastric junction presents an increasing incidence. Surgical resection with lymphadenectomy is the only curative treatment modality at the present time, but the optimal extent of lymphadenectomy is debatable. The aim of the present meta-analysis was to estimate the therapeutic value of each nodal station.

methodsStudies reporting the therapeutic value index of each nodal station in Siewert types II/III oesophagogastric junction (EGJ) were searched in PubMed, Web of Science and Embase up to October 2022. This index was calculated by multiplication of metastatic incidence and 5-year overall survival rate at each nodal station. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Prevalence Studies. Pooled metastatic incidence and therapeutic value index were calculated using RevMan 5.4.

resultsTwelve studies involving 3513 patients were included. Nodes No. 3, 1, 7 and 2 were routinely dissected and achieved a high (≥10) or moderate (5-10) therapeutic value index in decreasing order, due to their high metastatic incidence and favourable survival rate. The index was relatively low (2-5) in suprapancreatic nodes No. 9, 11p and 8a. The index for nodes No. 4d and 10 was relatively low in Siewert type Ⅲ EGJ but very low (<2) in type Ⅱ. The index was very low for nodes No. 5, 6, 11d and 12a, due to their low metastatic incidence and poor survival if positive. Para-aortic, parahiatal and mediastinal nodes were dissected only in highly selected cases. Dissection of the lower mediastinal nodes, especially No. 110, could improve survival rates in type Ⅱ EGJ.

conclusionThese data could help assess the optimal extent of lymphadenectomy for EGJ. Nodes No. 1, 2, 3, 7, 8a, 9 and 11p need routine dissection in both Siewert types Ⅱ/Ⅲ EGJ; nodes around the lower oesophagus (especially No. 110) in Siewert type Ⅱ EGJ and nodes No. 4d and 10 in Siewert type Ⅲ EGJ might be considered for dissection.
