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

The tumor microenvironment of hepatocellular carcinoma (HCC) is a complex system, involving mutual promotion and inhibition between cells and molecules. It results in alterations to inflammatory-associated factors, including a decrease in interleukin (IL)-2 and an increase in tumor necrosis factor, together with a characteristic elevation of IL-6. Following the synthesis and release of IL-6, HCC is stimulated through IL-6 binding to the IL-6 receptor (IL-6R). In the present study, immunohistochemistry was performed to investigate the expression levels of IL-6 and IL-6R in 92 patients with HCC, and the association between IL-6/IL-6R expression levels and tumor recurrence was examined. Notably increased expression levels of IL-6 and IL-6R were observed in the HCC microenvironment, and recurrence occurred earlier in patients with high IL-6/IL-6R expression levels compared with those with low expression levels (P<0.05). However, there was no significant difference in overall survival between patients in the two groups (P>0.05). Platelet levels <100×10
