Combined association of dietary fibre and cognitive function with all-cause and cause-specific mortality in older adults.
Article in Annals of medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundDietary fibre and cognitive function are associated with the risk of mortality, respectively. Inadequate dietary fibre intake and cognitive impairment frequently co-occur in older adults, but the combined effect of dietary fibre and cognitive function on mortality remains unknown. The study was to investigate the combined effect of dietary fibre and cognitive function on mortality over a 13-year follow-up in a representative of older adults from the U.S.
methodsWe analyzed data from two cycles of the National Health and Nutrition Examination Survey (NHANES) 1999-2000 and 2001-2002 with mortality follow-up data through 13 December 2015 obtained from Public-use Linked Mortality Files. Low dietary fibre intake was defined as the lowest quartile of dietary fibre intake. Cognitive impairment was defined as below the median of Digit Symbol Substitution Test. The separate and combined effects of low dietary fibre intake and cognitive impairment on all-cause and cause-specific mortality were assessed in older adults using weighted Cox proportional hazard models adjusting for potential confounders.
resultsA total of 2012 participants (weighted sample was 32,765,094) aged 60 years and older were enrolled in the study. After a median follow-up of 13.4 years, 1017 participants (50.4%) were identified as all-cause deaths, including 183 (9.1%) participants dying from cancer, 199 (9.9%) participants dying from cardiovascular disease, and 635 (31.5%) participants dying from non-cancer/non-cardiovascular disease. Participants with low dietary fibre intake and cognitive impairment had nearly twice the risk of all-cause (HR, 2.030; 95% CI, 1.406-2.931) and non-cancer/non-cardiovascular (HR, 2.057; 95% CI, 1.297-3.262) mortality, and over triple cancer (HR, 3.334; 95% CI, 1.685-6.599) mortality, compared to those without both.
conclusionsThe combination of low dietary fibre intake and cognitive impairment was associated with an increased risk of all-cause, cancer and non-cancer/non- cardiovascular mortality in older adults.
