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

Isocitrate dehydrogenase 2 (IDH2) is the rate-limiting enzyme in the tricarboxylic acid (TCA) cycle in cellular metabolism. Growing evidence indicates that IDH2 plays a crucial role in the development of cancer. We aimed to investigate the expression level of IDH2 and its prognostic value in esophageal squamous cell cancer (ESCC). We evaluate the IDH2 expression and prognostic value in ESCC by immunohistochemical (IHC) staining, quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. The cell counting kit-8 (CCK8), clonogenic and invasion assays were performed to verify the IDH2 function in vitro. The protein expression level of IDH2 was significantly upregulated in ESCC tissues (IHC, Western blotting, all
