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

Electrocatalytic hydrogenation (ECH) of 5-hydroxymethylfurfural (HMF) to 2,5-bis(hydroxymethyl)furan (BHMF) is regarded as a green synthesis strategy for generating high quality bio-based chemicals. However, simultaneously regulating both the hydrogen (H) coverage and the adsorption behavior of HMF presents a significant challenge, particularly in unraveling the intricate structure-activity relationship and achieving a selective target product. Here, we enhance the availability of hydrogen (H*) and modulate surface electronic interactions with 5-hydroxymethylfurfural (HMF) to facilitate selective electrochemical hydrogenation (ECH) of HMF by introducing palladium as an auxiliary component. Pd-Cu dual sites synergistically enhanced H* supply and HMF activation while suppressing the competing hydrogen evolution reaction. The optimized electrocatalyst exhibits notable catalytic performance, attaining a selectivity of 99.3% and a faradaic efficiency of 97.5% for BHMF at a potential of -1.15 V (
