The effectiveness of vitamin D supplementation in alleviating diabetes distress among patients with vitamin D deficiency at hospital putrajaya: an open label randomised controlled trial.
Trial report in Endocrine, 2025. 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/
objectivesDiabetes distress (DD) is significant emotional reactions to the diagnosis, threat of complications, self-management demands, and unsupportive social structures. Vitamin D (VitD) supplementation benefits various mood disorders but its role on DD remained unproven. We aim to study the effect of VitD supplementation on DD among patients with VitD deficiency.
methodThis was a prospective, open-label randomized intervention study conducted in Putrajaya Hospital using validated Diabetes Distress Scale 17 (DDS17). The DDS17 addresses four subdomains – A (Emotional burden), B (Physician-related distress), C (Regimen distress) and D (Interpersonal relationship distress). Mean score ≥ 2 is considered DD worthy of clinical attention. Convenience sampling was adopted followed by simple randomization into intervention or control arm. Outcome measures are collected prospectively at baseline and after 16 weeks of study duration.
resultsThere were 80 participants (71.3% female, 71.3% Malay) with mean age of 47.9 years recruited. Baseline demographic and diabetic profiles showed no significant difference between arms. VitD improved from 25.3nmol/L to 56.8nmol/L in intervention arm (n = 40) while participants in control arm (n = 40) remained VitD deficient at 37.6nmol/L. Mean total distress score in intervention arm improved from 2.9 to 1.7 (p < 0.01). Significant improvement was noted between group for total DD (p = 0.027), emotional distress (p = 0.043) and regimen distress (p = 0.030). Significant DD improvement was found across all subdomains in the intervention arm regardless of baseline VitD level but no significant improvement in control arm participants with baseline VitD < 25nmol/L.
conclusionAdequate VitD supplementation is effective to improve DD, thus warrants consideration for people living with diabetes and VitD deficiency.
