Relationship of Cancer to Brain Aging Markers of Alzheimer's Disease: The Framingham Heart Study.

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
backgroundPrevious studies have demonstrated a strong inverse association between cancer and risk of Alzheimer's disease (AD). This study aimed to further investigate this association by examining measures of cognitive performance and neuroimaging.
methodsNeuropsychological (NP) test batteries consisting of quantitative measures of memory and executive function and volumetric brain magnetic resonance imaging (MRI) scans measuring brain and white-matter hyperintensity volumes were administered to 2,043 dementia-free participants (54% women) in the Framingham Heart Study (FHS) Offspring cohort from 1999-2005. History of cancer was assessed at examination visits and through hospital records. Linear regression was used to examine the association between cancer history and NP/MRI variables.
resultsThere were 252 and 1,791 participants with and without a previous history of cancer, respectively. Cancer survivors had an average time between diagnosis and NP/MRI exam of 9.8 years. History of any invasive cancer was associated with better executive function (Beta=0.16, p=0.04) but not memory function. Non-invasive cancer was not associated with any change in cognitive performance. Patients with prostate cancer had larger frontal brain volumes (Beta=4.13, p=0.03). Cancer history was not associated with any other MRI measure.
conclusionsWe did not find any strong evidence linking cancer to cognitive or neuroimaging biomarkers that would explain a lower risk of subsequent AD, although a previous FHS study demonstrated a strong inverse association between cancer and risk of AD. Future work should examine the association between cancer and other biomarkers of AD as well as more sensitive metrics of AD-related brain aging markers.
