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

Precise localization of auditory evoked fields (AEFs) from magnetoencephalography (MEG) data is very important for the functional understanding of the auditory cortex in medicine and cognitive neuroscience. The numerical solution of the field equations in the human head using the boundary element method (BEM) is a powerful tool for achieving this. The spatial resolution of the BEM is crucial for the achievable accuracy of localized neural sources. However, in classical BEM (as implemented, e.g., in MNE-Python), very high resolutions are impractical due to the associated prohibitive computational effort. In contrast, our recently introduced reciprocal boundary element fast multipole method (reciprocal BEM-FMM) allows for hitherto unprecedented spatial resolution of forward models. In this work, we employ reciprocal BEM-FMM to construct high-resolution forward models to localize AEFs. Simulated AEFs were generated using a direct BEM-FMM approach on realistic 40-tissue Sim4Life segmentations. Comparative analyses from simulated data demonstrate that high-resolution BEM-FMM forward models yield statistically superior source estimates relative to the 3-layer BEM. We also compare BEM-FMM forward models with source dipole resolution varying from 25,000 to 3,200,000 sources, and find that resolutions above 200,000 sources are sufficient for achieving accurate, high-resolution source estimates. We therefore recommend using the high-resolution reciprocal BEM-FMM to utilize high spatial anatomical precision for the modeling of neural activity.
