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 influence of temperature on the product distribution during fructose conversion was systematically investigated using Ce-(P), Nb-(P), CeNb5-(P), CeNb15-(P), and CeNb25-(P) materials prepared by the Pechini method. Reactions were performed in aqueous medium for 2 h at temperatures ranging from 130 to 160 °C. Increasing temperature enhanced fructose conversion but also modified the relative contributions of dehydration, fragmentation, and consecutive degradation pathways. Nb-(P) reached the highest fructose conversion, increasing from 17.6% at 130 °C to 67.9% at 160 °C, but also exhibited a greater contribution from unidentified and degradation products under the most severe conditions. In contrast, the Ce-Nb mixed oxides, particularly CeNb15-(P) and CeNb25-(P), more effectively directed the identified soluble products toward 5-hydroxymethylfurfural (5-HMF), while limiting some competing pathways. The formation of C3 compounds, including dihydroxyacetone and pyruvaldehyde, indicates the occurrence of C-C bond cleavage reactions, whose contribution increased with temperature and depended on material composition. The observed product distributions result from the combined influence of temperature, acid-site nature, concentration, strength, and accessibility, together with the redox properties of the Ce containing materials. These findings demonstrate that the principal contribution of the studied oxides lies in their catalyst dependent modulation of the fructose reaction network rather than in the effect of temperature alone.
