Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Single-atom catalysts (SACs) enable greener and more economically sustainable chemical production by significantly improving thermocatalysis efficiency and selectivity through maximized atom utilization and highly homogeneous metal coordination environments. Unfortunately, SACs are fundamentally constrained by the stability owing to the severe aggregation of single atoms, especially under the high-temperature thermocatalysis operations, which compromises the overall catalytic performance. Here, we report a synthetic strategy to realize the highly thermal-stable SACs resistance to sintering at harsh conditions through harnessing the inherent metal affinity and fluidity of liquid metal. A stable liquid metal-active metal interaction is formed, profiting from the superior metal affinity of liquid metal. Combined with the fluidity of liquid metal, active metal atoms can move but remain confined to the liquid metal as the metallic single-atom state at high temperatures. This catalyst exhibits outstanding thermal durability for ethane dehydrogenation, sustaining stable operation for over 100 h at 650 °C with an impressive ethylene selectivity of 98%. The strategy of constructing stable metal-metal interactions by utilizing the inherent metal affinity and dynamic fluidity of liquid metal will pave a practical way for the design of highly thermal-stable SACs.
