Neural antecedents of emotional disorders: a functional magnetic resonance imaging study of subsyndromal emotional symptoms in adolescent girls.
Article in Biological psychiatry, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundEmotional symptoms (ES) emerge forme fruste in adolescence, before manifesting as fully fledged emotional disorders. Studies indicate that subsyndromal ES precede the onset of emotional disorders. We hypothesized that adolescents showing subsyndromal ES will show perturbations in the emotion regulatory frontolimbic network (FLN) during emotion processing.
methodsFifty-eight female adolescents underwent functional magnetic resonance imaging while viewing an image-based emotion-processing task. Within this sample, 33 (56.9%) displayed emotional symptoms and 25 (43.1%) did not. Clinical measures, including assessments of mood and anxiety, were administered and participants were allocated to one of two groups based on the presence (ES+) or absence (ES-) of subsyndromal ES. Group comparisons were used to identify differential patterns of neural engagement and their relationship to clinical variables.
resultsGroups displayed emotion-specific differences in FLN activity with increased frontal activity in ES+ girls during positive emotion processing and decreased frontal and limbic activity during negative emotion processing. Trait anxiety was the strongest clinical predictor of group membership (ES+ versus ES-) and displayed a significant negative correlation with hippocampal neural activity during negative emotion processing. In addition, between the groups, the hippocampus displayed a pattern of reverse coupling with the amygdala and insula that was also significantly correlated with trait anxiety.
conclusionsThere is divergence in the pattern of FLN neural processing in adolescent female subjects determined by emotional symptoms. Future research is needed to corroborate these findings and to underline their implications longitudinally.
