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/

aimPostoperative chemotherapy is an absolutely imperative treatment for advanced esophageal cancer patients, while preoperative chemotherapy is the standard therapy for clinical stage II/III esophageal squamous cell carcinoma (ESCC) in Japan. The aim of this study was to report the effect of postoperative chemotherapy on survival after esophagectomy due to thoracic esophageal squamous cell carcinoma. PATIENTS AND

methodsOne hundred thirteen consecutive patients with esophageal carcinoma who underwent esophagectomy were included. Several regiments were performed at various times.

resultsAdjuvant chemotherapy brought a significantly superior overall survival (p=0.002), although there was no significant difference in cancer-specific survival (p=0.054) for clinical stage II or stage III esophageal cancer patients. Depth of invasion (p=0.003), number of lymph node metastases (p=0.048), and venous invasion (p<0.001) were risk factors for recurrence in the adjuvant-chemotherapy group with positive lymph nodes. Additionally, a not well-differentiated type, lymphatic and venous invasions were risk factors for recurrence in the surgery-alone group without positive lymph nodes.

conclusionPostoperative adjuvant chemotherapy contributes to the prognosis of clinical stage II or III esophageal cancer patients.
