Association of dietary fiber intake with all-cause and cardiovascular mortality in diabetes and prediabetes.
Article in Diabetology & metabolic syndrome, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeTo examine the association between dietary fiber intake and mortality risks (all-cause and cardiovascular) among U.S. adults with diabetes or prediabetes, and to evaluate the dose-response patterns of these associations. MATERIALS AND
methodsThis longitudinal cohort study analyzed data from 3259 adults with diabetes or prediabetes from the 2011-2018 National Health and Nutrition Examination Survey (NHANES). Dietary fiber intake was assessed using two 24-hour dietary recall interviews. Mortality data were obtained through December 31, 2019. Multiple Cox proportional hazards models were used to evaluate associations between fiber intake and mortality outcomes, adjusting for demographic and health-related covariates.
resultsHigher dietary fiber intake was significantly associated with reduced all-cause mortality risk (HR = 0.98, 95% CI: 0.97-0.99, P = 0.0039). For cardiovascular mortality, a non-linear relationship was identified with a threshold at 26.2 g/day. Below this threshold, each gram increase in fiber intake was associated with a 3% reduction in cardiovascular mortality risk (HR = 0.97, 95% CI: 0.94-0.99, P = 0.0352), while no significant benefit was observed above this threshold.
conclusionsDietary fiber intake shows a protective effect against all-cause mortality in U.S. adults with diabetes or prediabetes. For cardiovascular mortality, moderate fiber intake up to 26.2 g/day appears beneficial, while higher intake may not provide additional cardiovascular benefits. These findings provide important evidence for developing targeted dietary recommendations in diabetes management.
