The Influence of Negative Affect on Working Memory Updating of Food Stimuli Among Adolescents With Anorexia Nervosa.

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
objectiveDifficulty updating information in working memory has been proposed to underlie ruminative thinking in individuals with anorexia nervosa (AN). However, evidence regarding updating difficulties in AN remains inconclusive, particularly among adolescents. It has been proposed that exposure to negative emotion and disorder-salient stimuli may uniquely influence updating in AN. This study examined the influence of exposure to negative emotion on updating of food and non-food stimuli among adolescents with AN.
methodThe study included 41 female adolescents with restrictive AN (M
resultsMedium-to-large effects revealed significantly higher updating errors among adolescents with AN compared to controls for food targets and after exposure to negative stimuli. In contrast, during exposure to both negative images and food targets, the groups performed similarly, as this condition also increased updating errors among controls. Additionally, a higher proportion of updating errors was associated with greater eating disorder symptoms severity. DISCUSSION: The findings indicate that exposure to negative emotion and food stimuli separately compromise working memory updating in adolescents with AN. These results underscore the role of environmental triggering cues in compromising working memory updating in AN and highlight the importance of considering ecological cues when evaluating cognitive functioning in eating disorders.
