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.

2 · The registry

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

backgroundThis study investigates the association between single-nucleotide polymorphisms (SNPs) in the MMP-1, MMP-8, and MMP-13 genes and the risk of oral mucositis development in paediatric patients with leukaemia and lymphoma who are undergoing methotrexate (MTX) treatment. MTX is associated with inflammatory effects and oxidative stress, which activate MMPs, enzymes responsible for degrading the extracellular matrix. This study aimed to investigate the association between MMPs polymorphisms (rs1799750, rs3025058, and rs2252070) with OM in the oncopediatric patients treated with MTX.

methodsGenomic DNA from 100 patients was extracted from saliva and genotypes were obtained by PCR-RFLP. Genotype data were measured using the Chi-square test. Haplotype estimation, Hardy-Weinberg equilibrium, linkage disequilibrium, multiple logistic regression analyses was conducted using SNPStats and with R. MCA performed with the packages FactoMineR and factoextra.

resultsThe results show that the MMP-1 g.-1607 G>GG, MMP-8 g.-799 C>T, and MMP-13 g.-77 A>G polymorphisms are associated with the occurrence of oral mucositis. The MMP-8 g.-799 C>T polymorphism was also associated with greater disease severity.

conclusionsThe study highlights the importance of these MMPs polymorphisms as potential markers for predicting susceptibility to oral mucositis, suggesting that these data could help tailor treatments to minimise the occurrence and severity of mucositis.
