Associations of dietary fiber knowledge and intake with glycemic control among Jordanian patients with type two diabetes mellitus: a cross-sectional study.
Article in Food & nutrition research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Dietary fiber plays an important role in glycemic control, as reflected by glycated hemoglobin (HbA1c), among individuals with type 2 diabetes mellitus. However, evidence from Jordan regarding patients' knowledge of dietary fiber, consumption patterns, and perceived barriers to adequate intake remains limited. Objective: This study aimed to assess dietary fiber knowledge and consumption frequency among patients with type 2 diabetes mellitus, and to examine their associations with glycemic control and perceived barriers to adequate intake. Methods: A cross-sectional study was conducted among 722 adults with type 2 diabetes mellitus attending the National Center for Diabetes, Endocrinology, and Genetics in Amman, Jordan. Data were collected using a validated questionnaire that assessed dietary fiber knowledge related to food sources and health benefits (15 items), frequency of consumption of fiber-rich foods, and perceived barriers to intake. Glycemic control was evaluated using HbA1c levels. Results: Most fiber-rich food items showed no statistically significant association with glycated hemoglobin levels ( Conclusion: Better glycemic control among patients with type 2 diabetes mellitus is associated with higher dietary fiber knowledge; however, existing barriers may hinder the translation of knowledge into actual dietary practices. Educational interventions should emphasize practical and culturally appropriate strategies to support the incorporation of dietary fiber into daily diets. Future research should focus on closing the gap between dietary fiber knowledge and its effective application in diabetes management.
