IVW, Inverse variance weighted; nsnp, the number of single-nucleotide polymorphisms; Beta, the regression coefficient based on plasma omega-3 raising effect allele; SE, standard error; p < 0.05 represents the putative causal association of the increased levels of plasma omega-3 with low back pain; OR, Odds ratio; OR_lci95, Lower limit of 95% confidence interval for OR; OR_uci95, Upper limit of 95% confidence interval for OR.
