  1. Values are mean ± SD.
  2. MCV, mean corpuscular volume; MCHC, mean corpuscular haemoglobin concentration; RDW, red-cell distribution; ALT, alanine aminotransferase; ALP, alkaline phosphatase; GGT, gamma-glutamyltransferase; eGFR, estimated glomerular filtration rate; TSH, thyroid-stimulating hormone; T4, total thyroxine; CRP, C-reactive protein (highest post-operative levels). Leptin, adiponectin and resistin were measured in 284 patients (147 with cervical and 137 with trochanteric HF).
  3. All variables reflect data on admission (pre-operatively).
