Older age does not limit postbariatric surgery cognitive benefits: a preliminary investigation.

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
backgroundBariatric surgery is associated with cognitive benefits, but the nature of such gains may be variable across demographically and clinically diverse persons. Older adults achieve less weight loss and resolution of fewer medical co-morbidities after surgery compared to younger patients and are also at heightened risk for nutritional deficiencies. However, no study has examined the influence of age on cognitive improvements after bariatric surgery. The objective of this study was to determine the effects of age on cognitive function postbariatric surgery.
methodsA total of 95 participants enrolled in the Longitudinal Assessment for Bariatric Surgery completed a computerized cognitive test battery before bariatric surgery and at 12-weeks and 12-months postoperatively.
resultsBaseline cognitive impairments were common. Significant improvements were found in attention/executive function and memory abilities 12-weeks and 12-months after surgery. Age was not associated with baseline cognitive test performance. Separate multivariable regression analyses controlling for baseline attention/executive function and memory also showed that age was not a significant predictor of 12-week or 12-month performances in these domains (P>.05 for all).
conclusionThe present study provides preliminary evidence suggesting that older age does not preclude postbariatric surgery cognitive benefits. Prospective studies in more age diverse samples (i.e., up to 70 yr) are needed to determine whether bariatric surgery can reduce risk of age-related neurologic conditions like Alzheimer's disease and stroke.
