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
Covalent organic frameworks (COFs) offer modular architectures and ordered π-channels ideal for organic solar cells (OSCs), yet their integration is hindered by poor solubility and deficient film-forming rheology. Herein, a coordination-induced dispersion strategy is reported using vanadium ions to unlock the potential of COFs as high-performance hole transport layers (HTLs). By intercalating vanadium ions into a novel COF (TBpy), the metal centers act as "molecular wedges," increasing interlayer spacing to transform the rigid framework into a highly dispersible, solution-processable precursor. This coordination refines film morphology and fine-tunes the electronic structure, establishing a seamless cascaded energy alignment. Consequently, OSCs utilizing TBpy-V HTLs achieve a high power conversion efficiency of 21.03% and extraordinary durability (T
