Serum vitamin D levels in patients with lung metastases.
Article in Biomedical papers of the Medical Faculty of the University Palacky, Olomouc, Czechoslovakia, 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
BACKGROUND AND
aimVitamin D deficiency is linked to increased cancer risk and death but the effect of vitamin D substitution on the prognosis of patients with malignant disease is debatable. We aimed to investigate the value of serum vitamin D3 levels in patients with a history of malignancy and confirmed lung metastases. MATERIALS AND
methodSerum Vitamin D2 (25-hydroxyergokalciferol) and D3 (25‑hydroxycholekalciferol) levels were measured in 38 patients (28 with and 10 without lung metastases) using high performance liquid chromatography (HPLC). Serum Vitamin D2 + D3 levels of patients with lung metastases were analysed with respect to season, number of metastases, number of malignancies in the history, value according to the ASA (The American Society of Anaesthesiologists) physical status classification, and compared to patients with a history of malignancy without confirmed lung metastasis.
resultsOverall, mean serum vitamin D3 levels were significantly higher in summer (summer vs. winter; 85.06 nmol/L vs. 61.01 nmol/L; P=0.013). There was no significant difference in vitamin D3 levels in summer or winter between patients with or without lung metastases. There was also no significant difference in vitamin D3 levels in the summer months between patients with a history of one malignancy versus those with two or more. In winter however, patients with a history of one malignancy had significantly higher vitamin D3 levels (mean, 75.25 nmol/L) than those with two or more malignancies (mean 44.6 nmol/L) (P=0.027). The differences between vitamin D3 levels in patients with ASA 2 and 3 were not statistically significant.
conclusionVitamin D supplementation may be advisable for patients with a history of multiple malignancies, particularly during the winter months. However, confirmation in a clinical trial with a larger patient cohort is warranted before firm recommendations can be made.
