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

objectDevelopment of a reproducible and long-term stable reference phantom for MATERIALS AND

methodsThe phantom was built from readily available labware (50 mL centrifuge tubes, NMR glass vials) and 3D-printed holders, designed to ensure sufficient coil loading and excellent B

resultsThe reference solutions remained chemically and spectrally stable for up to 20 months under cooled, light-protected storage. Ethyl acetate provided a stable alternative to pyruvate, while gadolinium enabled the control of relaxation properties. Spectral assessment confirmed narrow linewidths, strong SNR, and reproducible peak separation across field strengths, validating the phantom's suitability for calibration and method development. DISCUSSION: This low-cost, open-source design provides a durable and reproducible
