Academic achievement map: a clear cognitive route and a promising motor path.
Article in Jornal de pediatria, 2026. 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
objectiveThis study investigates how executive functions, motor coordination, and oral discourse are related to academic performance in children from public schools in Rio de Janeiro.
methodThis longitudinal study assessed 75 children at the beginning (T1) and at the end (T2) of a school semester. Working memory was measured by the Digit Span test, eye-hand coordination by the Touch Test Disc (TTD), and oral discourse by non-semantic graph metrics (SpeechGraphs). Academic performance was assessed in Portuguese and Mathematics.
resultsDigit Span and TTD showed the strongest correlations with academic performance at T2, while graph metrics obtained from oral discourse were not significant predictors. Digit Span correlated positively with Portuguese (r = 0.505; p < 0.001) and Mathematics (r = 0.388; p = 0.002), while TTD correlated negatively with Portuguese (r = -0.453; p < 0.001) and Mathematics (r = -0.398; p = 0.001), i.e. better motor performance was associated with higher grades. Multiple regression analyses showed that Digit Span predicted Portuguese (β = 0.492; p < 0.001, 24.2% of variance). For Mathematics, both age (β = -0.501; p < 0.001) and Digit Span performance (β = 0.413; p = 0.002) were significant predictors.
conclusionWorking memory is a predictor of academic performance in both Portuguese and Mathematics, and eye-hand coordination also shows significant correlations with school grades, suggesting a relevant relationship between motor skills and learning. These findings highlight the importance of taking an integrated approach to cognitive and motor capacities in the educational context.
