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 total electron content is an integrated value of ionospheric electron density (Ne) along the satellite-receiver ray path; therefore, it cannot directly resolve ionospheric disturbances in the vertical direction. In this work, to better understand the continuous evolution of co-seismic ionospheric disturbances (CIDs) at different altitudes, we conducted an accurate three-dimensional (3-D) visualization of CIDs associated with the 2011 M9.0 Tohoku-Oki earthquake based on the computerized ionospheric tomography technique. The results clearly revealed the 3-D morphological discrepancies of CIDs caused by Rayleigh waves, acoustic-gravity waves originating from the epicenter, and internal gravity waves induced by the tsunami waves. Further, we investigated the propagation and distribution of Ne disturbances along altitude. It was found that Ne disturbances triggered by different wave patterns exhibited different evolution characteristics in the vertical direction. The application of 3-D ionospheric detection has the potential to enhance the robustness of the earthquake and tsunami early warning systems.
