Anticipatory and Consummatory Responses Across Reward Domains in 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
objectiveAnorexia nervosa (AN) is characterized by a tendency to limit intake of food, with specific restriction of foods that are generally considered highly palatable. This observation raises questions about whether reward processing is disturbed in AN. This study examined whether adolescents with AN differ from healthy control peers (HC) in anticipatory and consummatory reward processing.
methodAdolescents with AN (n = 71) and HC (n = 41) completed the Temporal Experience of Pleasure Scale (TEPS). The TEPS Anticipatory Pleasure scale was divided into two further subscales (Food and Non-food). Anticipatory (Food and Non-food) and Consummatory Pleasure (Non-food) scores were compared between adolescents with AN and HC using independent t-tests.
resultsTEPS scores were significantly lower among adolescents with AN than HC in Anticipatory Pleasure Food (t(110) = 7.80, p < 0.001) and Non-food (t(110) = 4.36, p < 0.001), and Consummatory Pleasure (t(110) = 2.60, p = 0.01) subscales. When controlling for BDI score, there was no significant group difference in TEPS Consummatory Pleasure scores (t(108) = 0.88, p = 0.38). Among adolescents with AN, Food Anticipatory Pleasure was significantly negatively correlated with all EDE-Q subscales and global score (r(68) = -0.38, p = 0.002) and positively correlated with food intake at a laboratory buffet meal (r(61) = 0.53, p < 0.001). DISCUSSION: Measures of both anticipatory and consummatory reward were reduced among adolescents with AN with a short duration of illness. In this study, eating disorder symptoms were related to diminished reward responses in anticipation of food. Dampened anticipatory reward response may comprise a mechanism of illness in AN that should be subject to further study.
