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

High-temperature dielectric films hold broad prospects in next-generation microelectronics and power systems. However, commercially available dielectric materials for electrostatic energy storage, specifically biaxially oriented polypropylene, suffer from drawbacks such as low energy density, low efficiency, and poor reliability, which limit the application of film capacitors in harsh environments. Herein, a series of naphthalene tetracarboxylic acid dianhydrides were incorporated into polyetherimide (PEI) backbone, thereby modulating the charge transport behavior. Specifically, synergistic regulation of traps and dihedral angles has effectively enhanced the breakdown strength of PEI. At 200 °C, the optimized dielectric film delivers a discharged energy density of 6.00 J cm
