Neurocognitive Profiles and Predictors of Symptom Trajectory During and After Treatment in Adolescent Bulimia 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
objectiveExecutive function deficits are well documented in anorexia nervosa and relate to poorer treatment outcomes, but their clinical relevance in bulimia nervosa (BN) is less clear. This study investigated associations between neurocognition and treatment outcomes in adolescents with BN using complementary hypothesis-driven and data-driven approaches.
methodsAdolescents with BN (N = 82) enrolled in a randomised controlled treatment trial completed the Delis-Kaplan Executive Functioning System (D-KEFS) and the Eating Disorder Examination (EDE). A priori executive functions investigated included cognitive flexibility, inhibition, problem-solving, and planning. K-means clustering derived neurocognitive profiles based on D-KEFS performance. Multilevel models examined whether a priori executive functions and cluster membership predicted trajectories of EDE Global Scores, objective binge-eating, and self-induced vomiting episodes from baseline to end-of-treatment and 6- and 12-month follow-ups, controlling for treatment condition (i.e., family-based treatment [FBT] versus cognitive behavioural therapy [CBT]).
resultsNone of the a priori executive function indices predicted any outcome (all ps > 0.050). K-means clustering identified two distinct neurocognitive profiles. Relative to Cluster 1 (high-average D-KEFS performance), individuals in Cluster 2 (low-average D-KEFS performance) exhibited a significantly higher frequency of self-induced vomiting across post-treatment timepoints (p = 0.049). DISCUSSION: Findings suggest that neurocognitive profiles may be more informative for predicting psychopathology in adolescent BN than individual executive function measures. Better overall performance on the D-KEFS may confer protection against higher purging frequency across time. Identifying neurocognitive profiles at intake may help identify adolescents at risk for elevated purging over time and inform tailored interventions to support treatment outcome.
