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 registryThe 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.

6 · The paper itselfAbstract
Electrocatalytic semi-hydrogenation reaction (ESHR) represents a promising sustainable production route, making the electrocatalytic synthesis of alkenol from alkynol at near-industrial current densities particularly significant. However, large current densities readily promote the competing hydrogen evolution reaction (HER), which consequently reduces the overall reaction efficiency. Here, we report a PdSb metallene (PdSb ene) electrocatalyst that overcomes this limitation by functioning as an efficient "active hydrogen reservoir". The p-d orbital hybridization induced by Sb incorporation modulates the electronic structure of Pd, which facilitates water dissociation, stabilizes H* intermediates, and steers the hydrogenation pathway toward thermodynamic favorability. Operating at a current density of -200 mA cm
