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

More complex occupations during adulthood may be associated with better cognition in later life. We used data from the Brazilian Longitudinal Study of Aging (ELSI) and the Mexican Health and Aging Study (MHAS) to investigate the association between occupational complexity and cognitive function. Using a regression-based approach, participants were classified as cognitively impaired or not. Occupation was categorized into four levels using the 2008 International Standard of Classification of Occupations. We used logistic regression models for separate and pooled analysis. The odds of cognitive impairment decreased with higher occupation skill levels in the ELSI, but this trend was not seen in the MHAS, where the highest skill level was not associated with cognitive impairment. ELSI participants had a lower probability of cognitive impairment compared to MHAS participants with the same occupation skill level. The results of this study suggest that programs addressing the negative consequences of lower-complexity occupations need to be tailored to specific regional contexts, considering their unique socioeconomic, cultural, and occupational landscapes.
