Graphical display of the relationship between year of primary surgery and risk of revision due to deep infection (with 95% CI) for all THAs, cemented THAs, uncemented THAs, and Charnley THAs with uniform antibiotic prophylaxis, adjusted for sex, age, diagnosis, prosthesis, operation room ventilation, duration of operation, type of fixation, and antibiotic prophylaxis.

Table 3. Number of primary THAs included and number of reported first revisions due to deep infection. Adjusted risk ratio estimates for sex, age, diagnosis, type of prosthesis, duration of operation, operation room ventilation, antibiotic prophylaxis systemically, and type of fixation. The risk factors are adjusted for all the other risk factors in addition to year of surgery.
