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 hydrogenation behavior of FeB type CeGe was investigated. Hydrogenation (deuteration) produces mixtures of two modifications, similar to hydrides of other FeB type phases LnTt (Ln = La, Ce, Nd; Tt = Si, Ge). P-CeGeD0.75(2) (Pnma, a = 8.1603(5) Å, b = 4.0938(3) Å, c = 6.2911(4) Å) crystallizes in the LaGeH structure type (filled FeB type), whereas C-CeGeD0.95(3) (Cmcm, a = 4.2958(2) Å, b = 11.9970(7) Å, c = 4.0885(3) Å) crystallizes in the ZrNiH structure type (filled CrB). Similar to CeSiHx the mixtures feature exceptionally high ferromagnetic ordering temperatures of 21.6(1) K for CeGeDx and 22.1(2) K for CeGeHx (x ≤ 1), with the effective magnetic moments of 2.44(1) μB (CeGeDx) and 2.38(1) μB (CeGeHx) being close to the free ion value of 2.54 μB of Ce3+. The hydrides (deuterides) were studied by neutron powder diffraction (NPD), thermal analysis and magnetic susceptibility measurements.
