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

BACKGROUND/

aimThe optimal extent of lymph node dissection for ampullary carcinoma is controversial. The aim of this study was to investigate the efficacy of lymph node dissection for ampullary carcinoma. PATIENTS AND

methodsBetween 2000 and 2020, a total of 75 patients undergoing radical resection for ampullary carcinoma were included. The efficacy index (EI) was calculated by multiplication of the frequency of lymph node metastasis (LNM) at the station and the 5-year survival rate of patients with metastasis at the station.

resultsOut of 75 patients, 14 had LNM. The EI for the peri-pancreatic head (station 13 and 17) and superior mesenteric artery (station 14) lymph node were 4.4 and 3.5, respectively. Whereas the peri-gastric (station 5 and 6), common hepatic artery (station 8), and liver hilum (station 12) lymph node stations had zero EI. Although the number of patients with the station 16 dissected was small (9%), the para-aortic (station 16) lymph nodes had the highest EI of 14.3 despite being distant lymph nodes.

conclusionWe identified the distribution of LNM and survival benefit of lymph node dissection for ampullary carcinoma. Our results suggest that the optimal extent of lymph node dissection for ampullary carcinoma could be reconsidered.
