Impact of Depression and Nicotine Dependence on Executive Functioning in Rural Older Adult Smokers: A Brief Report (NCT02510716).

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
introductionRural older adults are an underserved population with high rates of smoking and related morbidity and mortality. Age-related executive function deficits are common in older smokers; however, the association of depression and nicotine dependence on executive function has not been explored. This study addressed whether depression and nicotine dependence are related to executive dysfunction in rural older adult smokers.
methodsThe sample included 40 rural older adults recruited from two primary care clinics in North Carolina. Executive function was evaluated with the Behavioral Regulation Index (BRI), Metacognition Index, and Global Executive Composite (GEC) T scores from the Behavior Rating Inventory of Executive Function-Adult. Nicotine dependence and depression symptoms were assessed using the Fagerstrom Test and Center for Epidemiologic Depression Scale-10, respectively. Analysis of variance was used to explore whether depression and/or nicotine dependence influences executive function. Nondirectional tests were performed with significance set at .10.
resultsSmokers who screened positive for depression had significantly greater executive dysfunction than those who did not (BRI: p = .0003, Metacognition Index: p < .0001, GEC: p < .0001), and moderate/high dependence was associated with greater executive function deficits compared with those with mild dependence (BRI: p = .0942). Together, depression and nicotine dependence explained 50% of the variability of the GEC overall scores.
conclusionsExecutive dysfunction is common in rural older adult smokers and associated with depression and nicotine dependence severity. Futures studies should test the relationship of executive function and smoking cessation in the older adult population as it may have implications for cessation in this population.
