Cognitive and neural facets of dissociation in a traumatized population.
Article in Emotion (Washington, D.C.), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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.
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
Dissociative phenomena are frequently experienced by psychologically traumatized people. However, little is known about the cognitive profiles of highly dissociative traumatized individuals, and corresponding patterns of neural connectivity when attentional networks are engaged in the context of emotion. One hundred seventeen traumatized women completed the multiscale dissociation inventory (MDI) and neuropsychological testing; MDI scores were used to classify high- and low-dissociative participants. Forty-six participants also underwent fMRI during performance of an attentional control task that incorporates emotionally distracting images (Affective Number Stroop; ANS). Compared to low-dissociative participants, high-dissociative participants demonstrated better performance on an executive functioning task (F1,111 = 4.64, p = .03), worse performance on a task of visual memory (F1,111 = 9.52, p = .003), and similar performance on all other neuropsychological measures. In addition, dissociative symptoms were negatively correlated with functional connectivity between the amygdala and right anterior insula in response to trauma-related ANS trials. These findings indicate that highly dissociative traumatized people experience difficulties with attentional control in the context of emotionally evocative stimuli, but in a neutral context, their overall cognitive profiles are similar to low-dissociative people. Highly dissociative participants also demonstrated weaker connectivity between the amygdala and insula in response to trauma-relevant images. Evocative, trauma-relevant stimuli appear to disrupt neutral networks involved with attention to salient cues and interoception in highly dissociative traumatized individuals.
