Extracellular matrix gene variants and susceptibility to sport-related musculoskeletal injuries.
Article in Journal of applied genetics, 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
The extracellular matrix (ECM) plays a fundamental role in maintaining skeletal muscle structure and facilitating tissue repair following injury. Alterations in its composition can disrupt regeneration, promote fibrosis, and increase susceptibility to musculoskeletal injury. The aim of this study was to investigate whether the BGN (rs1042103), DCN (rs13312816 and rs516115), ELN (rs2071307), FBN2 (rs331079), MMP1 (rs1799750), MMP10 (rs486055), and MMP12 (rs2276109) polymorphisms, either individually or in combination, are associated with susceptibility to musculoskeletal injury. This study included 142 physically active Caucasian participants with a self-reported history of non-contact musculoskeletal injury and 133 participants without such a history. All the samples were genotyped using real-time polymerase chain reaction (real-time PCR). Associations between genotypes, haplotypes, epistatic interactions, and musculoskeletal injury risk were analysed. A nominally increased risk of musculoskeletal injury was observed in individuals carrying:(i) FBN2 rs331079: GC and CC genotypes(ii) MMP12 rs2276109: GG genotype(iii) BGN rs1042103: AG and AA genotypes(iv) DCN rs516115: AG genotypeConversely, the GG genotype of DCN rs516115 appeared protective compared to AA. No significant associations were found for the remaining polymorphisms or for DCN and MMP haplotypes. An epistatic interaction between DCN (rs13312816) and BGN (rs1042103) was detected. Participants with AG/TT and AA/AT genotype combinations had a higher probability of belonging to the injury group. However, across all analyses, no associations remained statistically significant after Bonferroni correction. Specific genotypes of FBN2, MMP12, BGN, and DCN genotypes showed nominal associations with susceptibility to musculoskeletal injury in a physically active Caucasian population; therefore, these findings should be regarded as exploratory.
