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

introductionSex differences in dementia-related neuropathology are understudied in diverse populations.

methodsWe analyzed sex differences in neuropathological and cognitive data from the Brazilian Biobank for Aging Studies. Cognitive performance was evaluated with the Clinical Dementia Rating-Sum of Boxes (CDR-SOB). Linear and logistic regression models were conducted, including interaction terms for age, race, and education.

resultsIn 2229 participants (50.7% female, mean age ± SD 75.4 ± 12.3 years, 62.1% White), female sex was associated with a higher odds of AD pathology (Braak: odds ratio [OR] = 1.42, 95% confidence interval [CI]  = 1.17-1.72; Consortium to Establish a Registry for Alzheimer's Disease (CERAD): OR = 1.58, 95% CI = 1.27-1.98), and trans-activation response (TAR) DNA-binding protein 43 (TDP-43) (OR = 1.77, IC 95% = 1.22-2.59), and lower odds of Lewy body disease (OR = 0.69, 95% CI = 0.51-0.95). Female participant had worse cognitive performance (β = 1.56, 95% CI = 1.03-2.10). Sex modified associations of Braak, CERAD, TDP-43, and cerebral amyloid angiopathy with cognition. Age also interacted with sex and pathology on CDR-SOB. DISCUSSION: Sex differences in the associations between sex and neuropathology suggest the need for sex-informed dementia research.
