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
Metal additive manufacturing often produces coarse columnar grains and elemental segregation, resulting in anisotropic mechanical properties and degraded corrosion resistance. We present a powder blending strategy using multicomponent carbides (MCCs) to overcome these limitations in 316L stainless steel. Upon dissolution, MCCs drive the self-assembly of uniformly distributed core-shell oxynitride-carbide nanoparticles, which sequester detrimental nitrogen/oxygen impurities and markedly refine austenite grain size from 43.9 to 2.1 micrometers. This unique microstructure control yields an excellent combination of strength and ductility. Crucially, the corrosion resistance is enhanced by suppressing chromium segregation via tungsten, niobium, and tantalum partitioning to the cell boundaries and facilitating the formation of a protective tungsten trioxide-rich passive film. This work establishes an instructive paradigm for metal additive manufacturing, demonstrating how MCCs' introduction can tailor nanoprecipitations, grain structure, and alloy chemistry to simultaneously improve strength and corrosion resistance in structural alloys.
