Vitamin D status in medical staff in a German university hospital in comparison to wasteworkers in Northern and its association to quality of life: a prospective four-arm cohort study.
Article in BMC public health, 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
backgroundVitamin D (25(OH) D) deficiency has a high prevalence in adults in Germany. Due to workplace conditions, hospital staff might be particularly at high risk. Therefore, we determined the 25(OH) D status of medical staff in regard to their field of activity compared to a group of outdoor workers with a focus on quality of life (QoL) and 25(OH)D associated risk factors.
methods25(OH) D was measured in February (winter) and September (late summer) 2021 in medical staff of a university hospital in northern Germany (inpatient vs. surgical vs. administrative workers), and in a group of outdoor waste collectors. QoL (SF-36 questionnaire), and potential factors influencing 25(OH)D-status were collected.
resultsFor n = 108 participants 25(OH)D was obtained at both time points. In February, mean 25(OH)D was 40.02nmo/l (SD 21.78). In September, mean 25(OH) D increased significantly to 68.25 nmol (SD 20.75). A significant positive association between 25(OH) D and age (p = 0.036), and with work experience (p = 0.036) was detected in February. In September, food supplement substitution and previous traveling were associated with significantly higher serum 25-(OH)D level. There was no difference between the fields of activity, nor an association between 25(OH)D status and QoL.
conclusionDespite the expertise of medical staff, data seems to indicate an inadequate 25(OH)D supply among most medical staff and even outdoor workers, which is significantly more pronounced in winter. In addition to healthy sun seeking and eating habits, occupational health physician coordinated educational work and/or Vitamin D supplementation could be adequate interventions to optimize vitamin D supply.
