Biochemical parameters over the study day for study 3. (a) Plasma phosphorus, (b) ionised calcium (iCa) and (c) parathyroid hormone (PTH). Diet H (Inline graphic): 3·79 g total phosphorus/4184 kJ (1000 kcal), no added inorganic phosphorus, calcium:phosphorus 1·6. Diet I (Inline graphic): 3·86 g total phosphorus/4184 kJ (1000 kcal), 1·5 g phosphorus from sodium dihydrogen phosphate/4184 kJ (1000 kcal), calcium:phosphorus 1·59. Diet J (Inline graphic): 3·52 g total phosphorus/4184 kJ (1000 kcal), 1·5 g phosphorus from sodium tripolyphosphate/4184 kJ (1000 kcal), calcium:phosphorus 1·7. Values are means, with 95 % CI represented by vertical bars. *Mean values were significantly different from baseline (P <0·05). Reference ranges are shown for each parameter. Significant differences between diets: false (Inline graphic) and true (Inline graphic).
