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.

Abstract

backgroundDespite increasingly radical surgery for esophageal carcinoma, many patients still develop tumor recurrence after operation. This study was designed to analyze the clinical and pathologic influencing factors of early recurrence in patients with histological node-negative (pN0 stage) esophageal squamous cell carcinoma (ESCC) after radical esophagectomy.

methodsA retrospective study on 112 consecutive pN0 stage ESCC patients who underwent esophagectomy with lymphadenectomy by the same surgical team from January 2004 to December 2010. There were 92 male and 20 female patients, aging from 36 to 80 years with a mean age of 60.3 years. The Cox proportional hazards model was used to determine the independent risk factors for recurrence within 3 years after the operation.

resultsRecurrence was recognized in 45 patients (40.2%) within 3 years after operation. The median time to tumor recurrence was 17.4 months. Locoregional recurrence was found in 38 patients (33.9%) and hematogenous metastasis in 7 patients (6.3%). However, locoregional recurrence accounted for 84.4% of all relapse patients. Recurrence closely correlated with tumor location, grade of differentiation, primary tumor stage (pT) and pathologic stage (χ2 = 6.380 to 18.837, p < 0.05). The Cox multivariate analysis showed that upper/middle thoracic location (OR = 1.092, p = 0.049) and pT3-4a stage (OR = 3.296, p = 0.017) were independent risk factors for postoperative locoregional recurrence.

conclusionLocoregional recurrence was the most common recurrence pattern of patients with pN0 ESCC within 3 years after operation. Upper/middle thoracic location and pT3-4a stage were independent risk factors for locoregional recurrence of pN0 ESCC after radical esophagectomy.
