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

High costs remain a significant barrier to the broader adoption of MRI systems. Eliminating the need for Faraday shielding would substantially lower installation costs and facilitate diverse deployment, but this necessitates controlling both the incoming electromagnetic (EM) interference detected by the receive (Rx) system and the outgoing EM radiation from the transmit (Tx) system, usually a body Tx coil. Multiple strategies exist to detect and mitigate the Rx interference, but little progress has been made in mitigating the Tx radiation. This study introduces a parallel transmit (pTx) strategy for reducing Tx radiation to below regulatory limits. At 0.5T, conventional circularly polarized (CP) birdcage coils produce H-field emissions at a 10-meter radius (H
