The odds ratio and 95% confidence interval for odds ratio of the association of postsurgery complication with total hip arthroplasty revision resulted from the logistic regression model

Complication	Univariate OR (95% CI for OR)	Crude multivariable OR (95% CI for OR)	Adjusted multivariable OR (95% CI for OR)*
Prosthetic infection	55.242 (25.585-119.276)	79.231 (25.986-241.576)	44.339 (8.623-227.980)
Instability	50.848 (23.984-107.804)	55.896 (18.956-170.774)	57.790 (11.964-279.137)
Aseptic loosening	8.609 (3.244-22.849)	5.119 (1.239-21.146)	9.620 (1.581-58.527)
Periprostatic fracture	28.207 (12.056-65.997)	12.128 (3.405-43.193)	9.995 (1.477-67.639)
