Exploring Memory Compensation in Dyslexia: Strengths and Weaknesses in Memory Patterns Among Children and Adolescents.
Article in Child psychiatry and human development, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDeclarative memory plays a crucial role in learning and may serve as a compensatory mechanism for phonological deficits in individuals with dyslexia. However, research on its variability within this population remains limited. This study aimed to identify distinct declarative memory profiles in children and adolescents with dyslexia and examine their potential compensatory role.
methodsA total of 714 participants aged 10-19 years, including 136 individuals with dyslexia and 578 neurotypical controls, completed the Test of Memory and Learning Second Edition (TOMAL-2). A Latent Profile Analysis was used to identify memory subgroups based on six TOMAL-2 indices. Group differences were analyzed using independent samples t-tests, and logistic regression was conducted to assess the predictive utility of memory indices for dyslexia classification.
resultsFour distinct declarative memory profiles emerged: Typical Memory Performance (78%), Divergent Memory Abilities (11%), Globally Impaired Memory (8%), and Verbal Delayed Recall Impaired Memory (3%). While most individuals with dyslexia exhibited typical declarative memory performance, they were significantly more likely to belong to the Divergent Memory Abilities or Globally Impaired Memory profiles compared to the controls. The logistic regression analysis revealed that lower sequential and free recall scores, combined with stronger nonverbal memory, were significant predictors of dyslexia.
conclusionsThese findings highlight the heterogeneity of declarative memory in dyslexia, demonstrating that while some individuals rely on memory strength to compensate for phonological deficits, others experience broader memory impairments. This variability underscores the need for personalized interventions that leverage declarative memory strength while supporting those with deficits. Future research should explore longitudinal changes and cross-linguistic differences for targeted educational strategies.
