1 · What the graph read from it

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.

2 · The registry

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

objectiveEarly-life socioeconomic factors, such as education, closely associated with the opportunity to become multilingual (ML), are important determinants of late-life cognition. To study the cognitive advantage of multilingualism, it is critical to disentangle whether cognitive benefit is driven by multilingualism or education. With rich linguistic diversity across all socioeconomic gradients, India provides an excellent setting to examine the role of multilingualism on cognition among individuals with and without education.

methodUsing data from the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia, we evaluated the association of multilingualism by language similarity (i.e., speaking languages from the same or different language families) and education with cognition. Longitudinal Aging Study in India-Diagnostic Assessment of Dementia is a nationally representative sample of older Indian adults aged 60 and over, speaking 40 different languages and dialects (N = 4,088, 54% without formal schooling). Multilingual participants were categorized whether they spoke ≥2 languages within the same (classified as ML1) or different (classified as ML2) language families. Participants completed a comprehensive cognitive assessment assessing the domains of executive functioning, language, memory, and visuospatial ability.

resultsEducation stratified regression models adjusted for relevant covariates in the full sample and in a propensity-score matched sample. Among those with education, multilingualism was associated with better cognitive functioning across all domains regardless of language family (all p's < .05). Among those without education, only ML1 (not ML2) was associated with better executive functioning (B = 0.17 [0.07, 0.27]) compared to monolinguals.

conclusionsThese findings add to the growing literature on cognitive advantage of multilingualism, disentangling them from education and suggesting differential effects by language similarity. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
