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

Graphitic carbon is highly valuable due to its versatile applications in industry, and coal-derived graphitic carbon represents a significant and abundant resource. Electrical conductivity is a critical parameter for its performance during utilization. In this study, the carbon structural features and electrical conductivity of both naturally graphitized coal series and synthetic series produced by high-temperature treatment were comparatively studied by using X-ray diffraction (XRD), Raman spectroscopy, high-resolution transmission electron microscopy (HRTEM), etc. Structures of coal-derived graphitic carbon become more ordered with increasing metamorphic degree or pyrolysis temperature. Multiple nanoscale graphitic carbons co-occur within a single sample during graphitization, suggesting that graphitization is not a homogeneous process. The raw anthracite exhibits extremely low electrical conductivity (electrical resistivity is 1.899 × 10
