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

The peculiar molecule-structural units with ferroelectric ordering render poly(vinylidene fluoride) (PVDF) a crucial functional polymer, but the existence of the free volume in PVDF (also for many other polymers) would interrupt the long-range molecule chains, leading to the declined electrical functionality (e.g., electric breakdown), and also the thermal, mechanical, and chain relaxation properties. Herein, to regulate the free volume for electrical tuning, a molecular spatial-positioning shimming strategy is developed in terms of intercalating shortchain molecules polyethylene wax (PE wax) into the spherulite gap region of PVDF. The PE wax/PVDF films are fabricated by a multi-layer folding coupled hot pressing route that allows the complex crystalline structure modulation (e.g., phase, morphology, spherulite formation, amorphous and free-volume status etc.), which are comprehensively investigated. Upon free volume regulation, the fabricated PE wax/PVDF film exhibits significantly improved breakdown strength (E
