A cross-sectional study on the assessment of COLL11A1, VEGF, and GDF5 gene polymorphisms in Turkish patients with primary knee osteoarthritis.

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
backgroundThis study aimed to assess the relationships between knee OA (KOA) and the genes encoding collagen type XI-alpha1 (COL11A1), vascular endothelial growth factor (VEGF), and growth differentiation factor-5 (GDF-5), which have recently been investigated for their role in the pathophysiology of KOA in a Turkish Population.
methodsThis study included 100 patients who underwent surgery for KOA at Pamukkale University Medical Faculty's Orthopedics and Traumatology clinics and 100 volunteers with knee pain but without radiological evidence of KOA as a control group. Knee radiographs were assessed, and blood samples were collected from both groups for gene polymorphism analysis, with a focus on COL11A1 rs4907986, COL11A1 rs1241164, VEGF rs833058, and GDF5 rs143383.
resultsOur findings revealed no statistically significant difference between the KOA and control groups for COL11A1 rs4907986 and rs1241164. However, COL11A1 rs4907986 was found to be more common in women. The VEGF rs833058 polymorphism did not significantly differ between the KOA and control groups, although the equal distribution of homozygous polymorphisms in both groups suggests its potential utility in diagnostic considerations. Similarly, no significant difference was observed for the GDF-5 rs143383 polymorphism. However, this polymorphism was more frequent than the wild type in both groups, suggesting its potential association with KOA and its possible utility as an early diagnostic marker.
conclusionWhile no significant associations were found between COLL11A1, VEGF, or GDF-5 polymorphisms and KOA, the findings highlight the prevalence of GDF5 rs143383 in both groups, suggesting its potential role in the pathogenesis of KOA and its utility as a diagnostic marker. Further research is needed to better understand the genetic factors involved in KOA. CLINICAL TRIAL NUMBER: Not applicable.
