1 · What the graph read from it

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 registry

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

Expanding the library of polarity-engineered polymers is essential for enhancing performance and designing the flexibility of triboelectric nanogenerators (TENGs). Herein, we report a polyimide (PI) film derived from an imidazolium-mediated cross-linked 6FDA-durene polymer, with bromine anions as counterions, enabling surface polarity modulation and improved charge transfer. XPS and FT-IR analyses confirm the formation of imidazolium-mediated crosslinks in the 6FDA-durene polyimide, verifying the successful incorporation of ionic liquid groups into the polymer structure. Density-functional theory (DFT) calculations reveal that imidazolium crosslinking shifts the HOMO upward by 1 eV, lowering the electron-transfer barrier and switching the triboelectric polarity from negative to positive. The fabricated TENG achieves a power density of 85.67 mW/m
