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

X-ray ptychography has emerged as a powerful imaging tool on X-ray synchrotron facilities. Implementation of ptychography on laboratory-scale X-ray sources has largely been hindered by their poor temporal coherence and low flux. Here we propose an ultra-broadband method incorporating structured illumination to enhance the robustness of ptychography to broadband sources. Different from other methods, our ultra-broadband ptychography method enables imaging of dispersive samples without prior knowledge of light spectra. A 60% bandwidth light source and a high harmonic extreme ultraviolet source were used to validate our method. Moreover, our method demonstrates precise quantitative phase imaging capabilities. The proposed method will significantly advance the implementation of ptychography on laboratory-scale broadband X-ray sources and widen its applications in biomedicine and materials science.
