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

We proposed a simple approach to optimize a concentric-loops RF coil, consisting of an inner primary coil as the driving coil and an outer secondary coil as a passive resonator. By adjusting the tuning capacitor in the secondary loop to raise its self-resonance frequency to be slightly above the operating Larmor frequency, we enabled the preferred operation condition (additive mode), where both secondary and primary loops contributed to the largely enhanced RF coil transmit and receive magnetic fields (B
