Diet and diet-related challenges with specific focus on carbohydrates and carbohydrate counting in adults with type 1 diabetes: a cross-sectional study.
Observational study in BMJ open, 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
objectivesTo explore dietary intake, diet-related challenges in glucose management and perceived needs for dietary support among Swedish adults with type 1 diabetes (T1D).
designCross-sectional observational study based on an electronic survey that included the validated Meal-Q food frequency questionnaire and additional questions on dietary habits and management. Participant characteristics were retrieved from the Swedish National Diabetes Register. Descriptive and correlation analyses were conducted.
settingThree diabetes specialist clinics in Sweden.
participants375 adults with T1D.
main outcome measuresDietary intake and diet-related challenges in glucose management.
resultsA total of 191 persons (mean age 48 years; 48% female) consented to participate. The mean (SD) glycated haemoglobin A1c was 56 (13) mmol/mol, mean glucose 8.8 (2.2) mmol/L, time in range (TIR) 64% (18%) and BMI 27 (4.3) kg/m²; 41% used insulin pumps. Mean carbohydrate intake was 183 g/day (41% of energy, E%). Fibre intake was 23 g/day (3.1 g/MJ), and saturated fat intake was 29 g/day (15 E%), both inconsistent with dietary recommendations. About half (51%) found carbohydrate counting challenging, with 53% estimating carbohydrate intake visually and only 18% using advanced methods. Additionally, 48% reported reducing carbohydrate intake, and 61% avoided certain carbohydrate-rich foods due to glucose management difficulties. Approximately 40% of participants reported insufficient dietary guidance from their healthcare providers since diagnosis, 33% expressed interest in further dietitian support and 39% believed dietary changes could improve glucose control.
conclusionsParticipants reported lower fibre intake and higher saturated fat intake compared with dietary guidelines. Many found carbohydrate counting and carbohydrate-rich meals challenging. One-third expressed a wish for additional dietary support. These findings highlight the importance of improving access to tailored dietary counselling in routine T1D care.
