Calcium and vitamin D supplement intake may increase arterial stiffness in systemic lupus erythematosus patients.

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
objectivesLow serum levels of 25-hydroxyvitamin D (25(OH)D) have been associated with a higher frequency of risk factors and cardiovascular disease. The aim of this study is to evaluate the association of 25(OH)D, cardiovascular risk factors, and subclinical atherosclerosis in systemic lupus erythematosus (SLE) patients.
methodForty-seven female SLE patients were studied. Data collected included demographics, SLE activity, disease damage, cardiovascular risk factors, and markers of subclinical atherosclerosis. Patient treatments and vitamin D and calcium supplementation (VitD-Ca) were recorded. Vitamin D deficiency was defined as serum 25(OH)D < 50 nmol/l measured by ultra-high-performance liquid chromatography. Atherosclerosis was assessed by measuring the carotid-femoral pulse wave velocity (PWV) by Doppler velocimetry and intima-media thickness (IMT) by B-mode ultrasound scanning.
results61.7% of patients were vitamin D deficient with a mean level of 31.91 ± 10.21 nmol/l. Serum vitamin D concentration was significantly higher in the 23 patients taking VitD-Ca supplements than that in patients not supplemented (p = 0.004). No significant association was found between 25(OH)D serum levels and cardiovascular risk factors, disease activity, or different treatments for SLE. A significant positive correlation was found between 25(OH)D levels, PWV (p = 0.02), and IMT (p = 0.01); moreover, patients taking VitD-Ca supplements presented an increased arterial stiffness.
conclusionPatients with arterial stiffness showed higher levels of serum vitamin D and most of them were on VitD-Ca supplements. Although prospective studies with a larger number of patients and follow-up are needed, our findings suggest that VitD-Ca supplementation may have effects on SLE patients' arterial stiffness.
