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

Due to its unique properties, various forms of graphite are one of the most widely utilized industrial materials. HIPC-1, a high-purity graphite certified reference material, was developed at the National Research Council of Canada as a calibrant for carbon isotope delta and carbon mass fraction measurements. The certified carbon isotope delta value was calibrated using ten reference materials and is reported on both the VPDB-LSVEC scale (-26.32 ± 0.11 ‰, k = 2) and the VPDB scale (-26.21 ± 0.11 ‰, k = 2). The expanded uncertainty includes contributions from characterization, coherence of the carbon isotope delta reference materials, and bottle to bottle homogeneity of HIPC-1. Elemental impurities and the mass fraction of carbon in HIPC-1 were determined using glow discharge mass spectrometry (GD-MS), and the certified value of the mass fraction of carbon is 0.999889 ± 0.000268 kg/kg (k = 2).
