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

Stress-induced fractures are recognized as a primary cause of degradation in a wide range of positive electrode active materials during battery operation. However, the state-of-the-art mechanistic understanding and strategy development often overlook the brittle nature of these materials, as well as the dynamic and localized characteristics of mechanical stress during the charge and discharge cycles of the cell. Here we present a shape-memory polymer nanocoating method using initiated chemical vapour deposition to dynamically delocalize concentrated stresses in various positive electrode active materials, including Ni-rich layered oxides with different Ni contents and LiFePO
