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

Personality traits are stable individual differences linked to important life outcomes including mental health, occupational functioning, and interpersonal relationships, yet their neural bases remain poorly characterized. Prior electroencephalography (EEG) studies have mainly examined isolated features such as spectral power or frontal asymmetry and have yielded mixed results. Building on recent work in connectome based predictive modeling, this study tested whether resting state EEG connectivity can predict Big Five personality traits in a nonclinical student sample. Resting state EEG (eyes open and eyes closed; about five minutes) was recorded from 115 healthy Chinese university students aged 18 to 28 years, who completed a psychometrically validated Chinese version of the Big Five Inventory 2. The exploratory CPM analyses reported here were conducted using eyes-open connectivity matrices derived from amplitude envelope correlation (AEC) and debiased weighted phase lag index (dwPLI) across canonical frequency bands. At the model-specific level, three CPM models yielded modest cross-validated correlations between observed and predicted trait scores: alpha-band AEC for Conscientiousness (r = 0.30, 95% CI [0.12, 0.45]), beta-band AEC for Extraversion (r = 0.25, 95% CI [0.08, 0.42]), and theta-band dwPLI for Neuroticism (r = 0.25, 95% CI [0.05, 0.41]). No association was observed for Agreeableness and only the Neuroticism model met the criterion under the trait-wise FDR framework applied within each trait. These exploratory findings suggest that eyes-open resting-state EEG connectivity may contain modest trait-related information, but the effects require replication in larger, independent samples before mechanistic, applied or translation implications can be considered.
