Serum 25-hydroxyvitamin D concentrations, well being, and presenteeism among hospital porters: a single-center cross-sectional study in Greece.
Article in Frontiers in nutrition, 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
Vitamin D deficiency is common among healthcare workers owing to indoor work, shift patterns, and limited sunlight, even in Mediterranean countries, yet evidence for hospital porters is scarce. This single-center, cross-sectional study assessed serum 25-hydroxyvitamin D [25(OH)D] concentrations and their unadjusted associations with psychological well being and presenteeism among hospital porters in a Greek tertiary university hospital in Alexandroupolis, Northern Greece, between March and June 2026. Of 46 eligible porters, 42 participated (91.3%). Serum 25(OH)D was measured by electrochemiluminescence immunoassay (ECLIA). Participants completed validated Greek versions of the WHO-5 Well Being Index and the Stanford Presenteeism Scale (SPS-6). Demographic, occupational, lifestyle, and clinical data, including BMI, were obtained from occupational-health records. The median 25(OH)D was 18.7 ng/mL (IQR 14.3-26.0), with 59.5% classified as deficient; mean BMI was 26.7 ± 3.7 kg/m
