 ONFH, osteonecrosis of the femoral head; SNP, single nucleotide polymorphism; OR, odds ratio; 95% CI, 95% confidence interval; AIC, akaike information criterion; BIC, Bayesian information criterion
 p values were calculated using logistic regression analysis adjusted by gender, age, smoking and drinking
 Bold indicate that p < 0.05 means the data is statistically significant
 ^{*}p indicate that after Bonferroni correction (p < 0.05/6) means the data is statistically significant
