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

Inorganic pyrophosphatase (PPA1) is an enzyme which has been found to be upregulated in various tumors, yet its profile in gastrointestinal cancers has not systemically investigated. In present study, gastrointestinal tissue microarrays were used to evaluate PPA1 expression and the association of PPA1 expression with clinical outcomes was determined for patients with gastric cancer by immunohistochemistry. Overexpression of PPA1 was observed in cancers of the esophagus, stomach, and pancreaticobiliary system. PPA1 was overexpressed in 143 cases (51.3%) of the 279 primary gastric tumors and was associated with larger size (> 3 cm), nodal metastasis and advanced clinical staging (P < 0.05). Moreover, survival analysis demonstrated that PPA1 expression was significantly correlated reduced overall of patients with gastric cancer. Therefore, PPA1 may serve as a potential biomarker of poor prognosis in patients with gastric cancer.
