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

backgroundSince the advent and the success of adjuvant medical therapy for human epidermal growth factor receptor 2 (HER2)-positive breast cancer in the form of trastuzumab there has been increasing interest in the development of similar therapies in other solid organ malignancies including gastric cancer and oesophageal cancer. Over the years, multiple observational studies have been inconsistent. Several meta-analyses have been published looking at the association between HER2 and gastric cancer and oesophageal cancer. This review aims to summarize the meta-analytic evidence for the association between HER2 in gastric and oesophageal cancer.

methodsA systematic search was conducted using MEDLINE, PubMed, EMBASE, Current Contents Connect, Cochrane Library, Google Scholar, Science Direct, and Web of Science.

resultsOf the articles selected, only nine studies met full criteria. Six of them reviewed the role of HER2 in gastric cancer and the remaining three reviewed its role in oesophageal cancer.

conclusionsThe current evidence regarding the role of HER2 is unclear. However, it clearly plays a key role in the pathogenesis of gastric and oesophageal carcinomas. Targeted therapy towards this subgroup (despite variable frequency and association with survival) would offer a mortality benefit and improve survival.
