An analysis based on the Mendelian randomization method exploring the correlation between creatinine and degenerative inter-vertebral disc disease
Objective Utilizing the Mendelian randomization model to explore the impact of creatinine levels on Degen-erative intervertebral disc disease.Methods Using bidirectional Mendelian randomization,this section evaluates the correla-tion between creatinine levels and Degenerative intervertebral disc disease.This study employed two independent public genetic databases from Genome-Wide Association Studies(GWAS),this study primarily evaluates the causal relationship using the re-sults of the Inverse-variance weighted method in Mendelian randomization analysis,with four additional methods serving as ref-erences.CochransQ test for heterogeneity,Mendelian randomization Egger-intercept test,and Mendelian randomization-PRES-SO method employed for detecting heterogeneity and pleiotropy;Leave-one-out analysis and sensitivity,with forest plots and fun-nel plots utilized for sensitivity detection;Radial-Mendelian randomization approach used for outlier detection.Results Creati-nine levels showed a significant positive causal effect on Degenerative intervertebral disc disease[IVW:OR=1.218;95%CI:(1.085,1.368);P=0.001,<0.05].Degenerative intervertebral disc disease has no causal effect on creatinine levels[IVW:OR=0.961;95%CI:(0.923,1.001);P=0.055,>0.05].Heterogeneity tests indicated no significant bias(P=0.081>0.05),and Pleiotropy tests showed a low level of bias(P=0.471,>0.05).Conclusion Elevated creatinine levels are a potential risk factor for degenerative intervertebral disc disease.
