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

purposeThe aim was to improve the sensitivity and robustness against B

methodsWe investigated two variants of phase-cycled bSSFP acquisitions, namely uniformly weighted multi-echo and acquisition-weighted chemical shift imaging (CSI) to improve the SNR of DMI in the brain after oral [6,6'-

resultsHigh-resolution whole-brain dynamic DMI maps were obtained for all acquisitions. The CSI variant of phase-cycled bSSFP achieved an average SNR increase of 16% and 25% for glucose and glutamate + glutamine (Glx), respectively, compared to the SNR-optimized vendor's standard CSI. Phase-cycling improved the bSSFP metabolite estimation and provided additional spectral encoding at the cost of a 10% to 20% SNR loss. Compared to the CSI variant of bSSFP acquisition, the multi-echo variant exhibited up to 35% lower SNR performance because of uniform k-space weighting and less efficient readout. However, it achieved higher resolutions than acquisition-weighted CSI protocols and showed several qualitative improvements.

conclusionWe demonstrated the feasibility of using two phase-cycled bSSFP acquisitions for off-resonance insensitive high-resolution [6,6'-
