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
Anode-free Na batteries offer the highest possible energy density but suffer from rapid capacity decay resulting mainly from the formation of Na dendrites and large volume change. Here, we design a functionalized porous Al current collector created through template-free electrodeposition and physical separation methods to modulate Na growth behavior. The controlled porous architecture, featuring interconnected ligament-channel networks, reduces structural stress and inhibits dendritic Na formation by lowering local current density and uniformizing ion flux. In addition, the abundant sodiophilic active sites boost reaction kinetics, decrease Na nucleation barrier, and subsequently manipulate homogeneous Na nucleation. Consequently, the porous Al host exhibits high reversibility of dendrite-free Na plating/stripping behavior. A proof-of-concept 4.3 V-class pouch cell achieves an energy density of up to 420.4 watt-hours per kilogram and stable cycling performance with 84.9% capacity retention over 100 cycles under anode-free conditions, providing a pathway for the design of anode-free Na batteries for practical applications.
