1 · What the graph read from it

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.

Abstract

Objective: To check if there is a link between good vitamin D levels in the blood and subclinical atherosclerosis in people on hemodialysis. Methods: Ninety end-stage renal disease patients undergoing regular hemodialysis were included in a cross-sectional study. Based on carotid intima-media thickness (CIMT), patients were grouped into Group A (n = 44) with normal CIMT and Group B (n = 46) with increased CIMT. Clinical assessments, laboratory parameters (serum vitamin D, lipid profiles, and inflammatory markers), and CIMT were measured using carotid ultrasound. The researcher compared students' t-tests with quantitative variables, while employing the Chi-square or Fisher's exact test with qualitative variables. Results: A positive correlation was observed between serum vitamin D and calcium (p = 0.010) and triglycerides (p = 0.025). Serum vitamin D showed a negative correlation with weight, serum alkaline phosphatase, and urea. No significant differences were found between the two groups in terms of demographic factors, BMI, hemodialysis duration, diabetes prevalence, or vitamin D supplementation. Group B exhibited elevated serum calcium levels (p = 0.008). Multivariate analysis found weight as an independent predictor of low vitamin D levels (p = 0.016). Conclusion: Serum calcium levels were significantly associated with CIMT; however, no correlation was seen between vitamin D levels and CIMT. Trial registration: registered at clinicaltrials.gov (ID: NCT07200804).
