Prevalence of micronutrients and plasma protein concentrations below the reference range. Data were based on 44 patients except for zinc (n = 37), selenium (n = 42), and albumin (n = 39). Reference ranges: ascorbic acid 28 – 85 μmol/L, retinol 0.7 – 1.75 μmol/L, β-carotene 0.9 – 4.6 μmol/L, 25-Hydroxycholesterol > 50 - 175 nmol/l, α-tocopherol/cholesterol > 2.2 μmol/mmol, zinc 11.5 - 19.4 μmol/L, selenium > 0.94 μmol/L, albumin [g/L] 35 – 53 (≤ 60 y), 34 – 48 (> 60 y), 33 – 47 (> 70 y), 31 – 45 (> 80 y), and prealbumin >15 mg/dL. None of the patients had an α-tocopherol status below the reference range.
