“…Some studies have reported an increased mortality after 30 days and one, five, and eight years of follow-up [ 11 , 12 , 16 , 17 ], while other studies did not conclude any difference in mortality for PD vs non-PD patients over a six-month and two-year period [ 14 , 18 ]. One of these studies [14] , however, found an absolute difference in mortality of 5% (39.3% vs 34.1%) after 2 years, which could have clinical relevance. Furthermore, the other study [18] conducted no time-toevent analysis despite investigating mortality after six months, and adjusted for different confounders (e.g., fracture type and year of admission), but not variables as age and sex like this study, which are known to influence results more.…”
