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

backgroundComplete resection of a gastric cancer and adjacent lymph nodes offers the only chance for cure of the disease. However, disease recurrence occurs in 22-51% of cases, and its prognosis is very poor. Many clinicians perform post-operative follow-up for these patients, although there is no consensus on the regimen, frequency of visits, mode of testing, or the rationale of a follow-up program. PURPOSE: The objective of this systematic review was to identify the evidence for surveillance in patients with resected gastric cancer, specifically examining the interval of follow-up and the modalities utilized.

methodsElectronic literature searches were conducted using Medline, Embase, and the Cochrane Central Register of Controlled Trials from January 1st 1998 to December 1st 2009. All search titles and abstracts were independently rated for relevance by a minimum of two reviewers.

resultsFive articles were selected. A total of 810 patients underwent post-operative follow-up. History and physical examination, hematological and chemistry profile, endoscopy (esophagogastroduodenoscopy [EGD]), and computed tomography (CT) were the most frequently employed modalities. CT detected the majority of recurrences in the included studies. The survival post-recurrence was significantly higher in the asymptomatic group compared with symptomatic group in three studies, but this may simply reflect lead-time bias. No differences in overall survival (OS) were found.

conclusionThe included studies failed to show an improvement in OS with more intense surveillance. Further prospective studies are required to determine whether a subgroup of patients may benefit from more intensive follow-up.
