Is There a Need for Vitamin D Supplements During Summer Time in Northern Germany? A Study of Hospitalised Fracture Patients.
Article in Nutrients, 2024. 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
BACKGROUND/
objectivesVitamin D is a key factor in bone metabolism, especially in patients who have suffered fractures, a group in need of a healthy bone metabolism. In Germany, a 70-year-old person requires 20 min of sun exposure daily for sufficient endogenous production in April. While this appears to be a sufficient period on paper, it raises the question of whether sufficient synthesis is achieved, given the time and the implementation of skin cancer prevention. Furthermore, it is necessary to determine whether self-medication is a safe option.
methodsThis was an analysis of vitamin D levels in patients with fractures over a one-year period. To avoid bias due to vitamin D intake, patients were divided into groups (self-medication, without, prescribed). The differences due to age, gender, fracture type and fluctuation over the year were analysed.
results613 patients with a mean age of 73 years (45-97) were enrolled. The mean vitamin D level across all groups was 51 nmol/L, with a mean of 40 nmol/L for patients without supplementation (
conclusionsThe majority of patients did not achieve sufficient vitamin D levels through endogenous synthesis and substitution did not lead to toxic levels. This suggests that substitution is reasonable and safe even during the summer months.
