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

introductionPatients with Type 2 diabetes experience cognitive and affective deficits linked to widespread functional brain alterations. However, previous meta-analyses of functional neuroimaging have primarily focused on the resting-state studies. While valuable, this approach may have overlooked the key neuronal mechanisms underlying these deficits.

methodsTo address this, we conducted a coordinate-level task-based meta-analysis of functional neuroimaging via a systematic search of Embase, PubMed, Medline, and Web of Science (December 2023), alongside task-based and task-free connectivity analyses using the BrainMap database. Activation likelihood estimations were applied to two task categories: that are, cognitive and affective. To control for biased results, we also conducted jackknife sensitivity analysis and within-paper combined experiments analysis as validation analyses.

resultsWe identified a cluster of activation in cognitive paradigm (18 contrasts, 153 foci, 767 subjects), with the middle frontal gyrus, part of the medial frontal cortex, as the peak region. For the affective paradigm (18 contrasts, 181 foci, 951 subjects), we observed both increased and decreased activities. Two increased clusters peak in the amygdala and middle temporal gyrus, while the three decreased clusters were inferior frontal gyrus, insula, and putamen. Follow-up connectivity analyses showed that these brain alterations were both task-specific and task-generic.

conclusionDespite the lack of uniformity across task, such domain-specific and domain-general patterns of alterations provide a more nuanced understanding of the cognitive and affective deficits in Type 2 diabetes patients. This highlights the varied neuronal mechanisms underlying these deficits.
