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

backgroundPost-concussion brain energy is important for recovery, and measuring energy markers with individual characteristics may clarify recovery mechanisms. PURPOSE: To examine the association between magnetic resonance spectroscopy (MRS)-based brain energy measures (creatine concentration) with sex and patient-reported outcomes after concussion.

methodsWe evaluated adolescents with a concussion ≤3 weeks post-injury. Participants underwent 3T short-echo single-voxel MRS using a 32-channel head coil. Point-resolved spectroscopy (TR = 2000 ms, TE = 30 ms, voxel size = 20 × 20 × 20 mm

results

conclusionPost-concussion sex differences in creatine concentrations were detected, as higher creatine levels moderately correlated with patient-reported outcomes. Creatine may reflect altered energy dynamics in the brain. The absence of a non-injured control group limits determination of whether these differences are concussion-specific or reflective of baseline physiology.
