Table 3 Univariable and multivariable logistic regression analyses regarding declined physical performance, functional ability and mobility classified by the hip fracture type

From: Pertrochanteric hip fracture is associated with mobility decline and poorer physical performance 4 to 6 months post-hip fracture

  1. The results for univariable and multivariable adjusted logistic regression were shown by odds ratios (OR) with 95% confidence intervals (CI). Multivariable analyses were adjusted for age, sex, American Association of Anaesthesiologists scores, living arrangements and mobility before fracture, need for mobility aid, diagnosis of cognitive disorder. N Number of patients with each test result, n Number of patients with low test result. Classification of outcomes: grip strength women < 16kg, men < 27kg vs. more, TUG < 20s vs. ≥ 20, EMS < 14 vs. ≥ 14, mobility level declined from prefracture level (yes vs. no), BADL 0–5 vs. 6, IADL 0–7 vs. 8
