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

Introduction: This study examined whether multilingualism modified the adverse effect of illiteracy on cognition among older Indian adults with low to no formal schooling. Methods: Data came from the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia ( Results: Illiteracy was negatively associated with cognition, while multilingualism was positively associated. While multilingualism did not buffer the association of illiteracy, it did increase the positive association of literacy with executive functioning and memory. Discussion: These findings highlight the detrimental effects of illiteracy on cognition, while multilingualism appears beneficial among older adults with low to no formal schooling. The benefits of multilingualism, however, were diminished in illiterate compared to literate older adults, suggesting that limited early-life educational opportunities can weaken its contribution to cognition.
