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

backgroundDirect three-dimensional imaging of radiation beams could enable more accurate radiation dosimetry. It has been previously reported that changes in T PURPOSE: We use an MRI linear accelerator (MR-Linac) to visualize radiation delivery through the real-time effects of dose on the spin-lattice magnetic relaxation time (T

methodsAn ultrapure water phantom and a 1% agarose gel phantom were irradiated and imaged on a 1.5 T Elekta Unity MR-Linac. Radiation plans were created using the Monaco treatment planning system. Images were acquired before, during and after radiation. A dual-echo Look-Locker inversion recovery pulse sequence was used for simultaneous dynamic T
