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

<p>Introduction: The glymphatic system (GS) is a brain-wide clearance pathway whose dysfunction has been implicated in cognitive decline. This study was designed to assess GS alterations in prediabetes and type 2 diabetes mellitus (T2DM) using multiple MRI-derived metrics and to examine their associations with cognitive performance.

methodsThis cross-sectional study was conducted from October 2023 to June 2024 at Nanfang Hospital, a tertiary care center. A total of 147 participants were recruited, including 52 patients with T2DM, 44 with prediabetes, and 51 healthy controls (HC). All participants underwent brain MRI, laboratory examinations, and cognitive function assessments. GS function was evaluated using MRI-derived metrics, including choroid plexus (CP) volume, perivascular space (PVS) volume, free water (FW) index, and the diffusion tensor imaging analysis along the PVS (DTI-ALPS) index. Group differences were tested with general linear models adjusted for sex, age, and education, and associations with clinical variables were evaluated using partial correlations.

resultsCompared with HC, prediabetes showed increased CP volume and FW index, without significant changes in DTI-ALPS index or PVS volume. T2DM showed reduced DTI-ALPS index, increased CP volume, and higher FW index, with unchanged PVS volume. In both groups, lower DTI-ALPS index and higher CP volume or FW index correlated with poorer cognitive performance.

conclusionPrediabetes and T2DM exhibit GS alterations, including reduced DTI-ALPS index and increased CP volume and FW index, which are associated with poorer cognition. GS metrics may serve as potential neuroimaging biomarkers for cognitive impairment in this population. </p>.
