  1. Data are mean ± SD.
  2. *Mean difference and mean absolute difference in (mmol/mol) can be obtained by multiplying values in (%) by 10.93.
  3. The presented parameters were calculated under the assumption that erythrocytes were eliminated from cultures in combination of the chronological and uniform modes.
