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

objectiveAs endoscopic approaches become more widely used to treat early-stage esophageal cancer, reliably identifying patients with less-aggressive tumors is paramount. We sought to identify risk factors for recurrence in patients with completely resected T1 esophageal adenocarcinoma.

methodsWe retrospectively analyzed a single-institutional database for all patients with completely resected pathologic T1 esophageal adenocarcinoma (1996-2016). Risk factors for recurrence were identified using competing-risk regression methods. Risk stratification was performed on the basis of known preoperative clinicopathologic factors; this model's discriminative power for overall survival was evaluated using a Cox proportional hazards model.

resultsOf 243 patients, 32 experienced recurrence. At a median follow-up among survivors of 4 years (range, 0.05-19 years), the 5-year cumulative incidence of recurrence was 15%, and median time to recurrence was 2 years (range, 0.26-6.13 years). On univariable analysis, submucosal invasion, N1 disease, poor differentiation, tumor length, lymphovascular invasion, and multicentricity were significantly associated with recurrence. On multivariable analysis, N1 disease (hazard ratio, 2.93; 95% confidence interval, 1.17-7.34; P = .022) and tumor length (hazard ratio, 1.44; 95% confidence interval, 1.12-1.86; P = .004) were independently associated with recurrence. Risk stratification showed that patients without lymphovascular invasion and a with median tumor length of 0.8 cm (range, 0.10-1.70 cm) had a <10% risk of recurrence and improved survival.

conclusionsPathologic T1 tumors have a 5-year cumulative incidence of recurrence of 15%. Nodal involvement and tumor length were independent risk factors for recurrence, whereas tumors <2 cm in length without lymphovascular invasion were associated with a low risk of recurrence.
