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 registryThe 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.

6 · The paper itselfAbstract
Separation membranes with inherent low-carbon properties are crucial for energy‒water sustainability but suffer from fouling issue and performance deficiency. Herein, a lotus-leaf-mimetic catalytic membrane is synthesized via 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP)-Co metal-organic intermediate layer-mediated MnO₂ mineralization, transforming hydrophobic polymeric membranes into unique self-cleaning membranes. The derivative abundant oxygen vacancies during hetero-phase mineralization boost their catalytic capability. The lotus leaf-mimicking nano/micro-water pockets at the interface enable the membrane operando flux recovery to reach 99.9%. Most interestingly, the membrane exhibited 24.8-fold greater antifouling ability and 10.6-fold greater recovery compared with the unmineralized membrane, significantly outperforming state-of-the-art membranes. The exceptional performance for water treatment is attributed to active catalytic antifouling coupled with hierarchical antifouling barriers. The computational simulations reveal electron-rich bell-like structures with electron-deficient metal cores. This work paves a way for the fabrication of biomimetic materials for efficient water treatment and beyond.
