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

purposeTo describe the impact of macroscopic magnetic field gradients (MFGs) in the phase-encoding direction on MR images acquired with an asymmetric spin echo (ASE) sequence with echo-planar imaging (EPI) readout.

methodsIn EPI, the center of k-space is read out at a shifted time point in the presence of phase-encoding direction MFGs. The ASE signal equation was extended to account for a locally varying temporal offset

resultsSimulated qBOLD parameters were substantially modified by the local

conclusionThe effects of phase-encoding-direction MFGs on volunteer ASE images is consistent with the proposed signal model and relevant for qBOLD measurements. This highlights the necessity to correct or mitigate in-plane MFGs in ASE EPI, such as using a high parallel-imaging factor.
