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

objectivesTo leverage a combination of cortical high-flow sign on arterial spin labeling (ASL) and cystathionine measurement using MATERIALS AND

methodsWe implemented pseudo-continuous ASL technique (post-labeling delay = 2000 ms) using a 3.0-T MRI scanner. Relative perfusion maps were generated by subtracting paired labeled images from control images.

resultsThe cortical high-flow sign was identified more frequent in O_IDHm-codel (7/12, 58.3%) than in A_IDHm-noncodel (3/18, 16.7%; p = 0.018). The cystathionine levels in O_IDHm-codel (1.50 ± 0.63 mM) was significantly higher than in A_IDHm-noncodel (0.85 ± 0.24 mM; p = 0.001). The area under the curve for distinguishing O_IDHm-codel from A_IDHm-noncodel using the presence of cortical high-flow sign, cystathionine levels, and their combination was 0.708 (0.509-0.908), 0.750 (0.553-0.947), and 0.875 (0.737-1.000), respectively.

conclusionThe presence of cortical high-flow sign on ASL, along with elevated cystathionine levels measured by 1H-MRS, could differentiate O_IDHm-codel from A_IDHm-noncodel.
