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
Stress critically influences the cycling and safety of lithium metal batteries, especially in pouch cell or pack configurations. However, intrinsic coupling between stress and swelling persistently obscures the fundamental understanding of stress-strain effects. Herein, through real-time stress control, we identify that electro-chemo-mechanical responses of industrial-level cells are directly linked to stress relief principles of Li negative electrode. Li dendrites can hardly penetrate separators due to the plastic collapse of porous Li deposits. While densification of collapsed deposits occurs at 0.1 ~ 0.2 MPa, the dense architecture necessitates stress relief through creep or plastic deformation. Crucially, the separator penetration-induced short circuit originates from plastic deformation of densified Li, under stress exceeding its bulk yield strength (~1 MPa). These stress relief principles enlighten us achieving the stress-optimized 27 Ah, 402 Wh kg
