The effect of depression on cognitive decline among Korean retirees.

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
Background: Little information is available on the characteristics of cognitive ability among retirees. This study aimed to identify factors associated with cognitive impairment among Korean retirees. Materials and Methods: We used data from the Korean Longitudinal Study of Ageing survey. A total of 1755 retirees aged 45 years or older who had normal cognition were followed up for 12 years to identify cognitive impairment. Stepwise multivariate logistic models were used to assess odds ratios (ORs) and 95% confidence intervals (CIs) for cognitive decline. Results: Well-known risk factors, such as age (OR, 1.07; 95% CI, 1.06-1.09), female sex (OR, 1.49; 95% CI, 1.08-2.04), low education (OR, 2.45; 95% CI, 1.91-3.14), and depressive mood (OR, 1.51; 95% CI, 1.16-1.97), remained significantly associated with cognitive decline. Sex-stratified analysis revealed that depressive mood was significantly associated with cognitive decline in male retirees only (OR, 1.90; 95% CI, 1.31-2.75). Conclusion: Our finding indicates that screening male retirees for depressive mood is required to retard cognitive aging.
