Association of Selective VDR Gene Polymorphisms with Diffuse Large B-Cell Lymphoma (DLBCL) in a South Indian Population.

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
backgroundThe prevalence of Diffuse Large B-Cell Lymphoma (DLBCL) in India ranges from 34% to 60%. The prognosis for DLBCL can vary widely depending on various factors, including vitamin D deficiency. Research suggests that low vitamin D levels may be linked to poor overall survival (OS) and progression-free survival (PFS) in DLBCL patients. Additionally, polymorphisms in the vitamin D receptor (VDR) gene, specifically the BsmI and TaqI alleles, have been significantly associated with disease prognosis. However, the association of VDR polymorphisms and vitamin D deficiency with DLBCL is yet to be explored. Therefore, this study aims to evaluate the association of VDR gene polymorphisms (BsmI, TaqI, FokI, ApaI) in DLBCL patients.
methodsIn this cross-sectional study, 50 treatment-naive DLBCL patients from southern part of India were included. 100 samples of unrelated apparently healthy controls were used as comparator. Demographic characteristics of DLBCL patients were recorded and SNPs in VDR (real time polymerase chain reaction) were assessed. All analyses were performed using SPSS (V26). P<0.05 was considered statistically significant.
resultsThe frequencies of mutant genotypes [TT- BsmI, AG- TaqI and AG- FokI] were significantly associated with a reduced risk of DLBCL, decreasing the risk DLBCL by 71% (OR=0.29, 95% CI= 0.105 to 0.807), 72% (OR=0.28, 95% CI= 0.133 to 0.608) and 70% (OR=0.3, 95% CI= 0.07 to 1.225). Additionally, comparison with other Indian studies and ethnic groups revealed significant distinctions in VDR genotypes. Further, the haplotype analysis of SNPs in the VDR gene revealed significant association of C-A-G-T haplotype (rs731236-rs7975232-rs1544410-rs2228570) with the disease phenotype.
conclusionThe study shows significant association of BsmI, TaqI, and FokI VDR SNPs with DLBCL.
