Effects of low (upper panel) and high Pi dietary intake (lower panel) without and with vitamin D3 on parameters of endothelial function and arterial elasticity
| Endothelial and Arterial Parameters | Baseline | W6 | W11 (Plus D3) | Recovery |
|---|---|---|---|---|
| Low Pi dietary intake | ||||
| Reactive hyperemia index | 1.67 (1.30 to 2.04) | 1.53 (1.30 to 1.86) | 1.76 (1.40 to 2.12) | ND |
| AI, % | −10.6 (−2.0 to −19.2) | −7.4 (−2 to −12.8) | −10.7 (−5.7 to 16.4) | ND |
| PWV, m/s | 5.1 (4.4 to 5.8) | 5.3 (4.5 to 6.1) | 5.1 (4.4 to 5.8) | ND |
| High Pi dietary intake | ||||
| Reactive hyperemia index | 1.93 (1.48 to 2.38) | 1.84 (1.60 to 2.08) | 1.86 (1.50 to 2.22) | 1.92 (1.70 to 2.14) |
| AI, % | −10.1 (−2.0 to 18.2) | −8.1 (−3.2 to −13.0) | −4.9 (+1.0 to 10.8) | −7.8 (0 to 15.6) |
| PWV, m/s | 5.7 (4.7 to 6.7) | 5.8 (4.9 to 6.7) | 5.7 (4.8 to 6.6) | 5.8 (4.9 to 6.7) |
Values are means with 95% CIs in brackets. Recovery measurements (2 mo after the high-Pi plus D3 period+1 week) were only performed in the high-Pi group. D3, vitamin D3; W, week; Pi, phosphorus.
