Summary of anthropometric measures for the 8 study patients at baseline and at the end of the 2 study periods
| Baseline | Low-normal pH | High-normal pH | P value1 | |
| Final arterial pH | — | 7.37 ± 0.012 | 7.44 ± 0.02 | <0.001 |

| Triceps skinfold thickness (mm) | 22.7 ± 7.2 | 21.6 ± 6.8 | 22.0 ± 7.2 | 0.63 |
| Biceps skinfold thickness (mm) | 8.0 (3.8)3 | 7.8 (1.4) | 8.2 (3.1) | 0.26 |
| Subscapular skinfold thickness (mm)4 | 19.6 ± 7.3 | 20.9 ± 6.5 | 20.8 ± 7.1 | 0.96 |

| Midarm muscle area (cm2) | 47.1 ± 8.9 | 46.9 ± 10.6 | 45.8 ± 10.2 | 0.54 |
| Midcalf circumference (cm)4 | 35.2 ± 3.2 | 35.3 ± 2.8 | 35.2 ± 3.6 | 0.97 |
| Midcalf muscle area (cm2)4 | 70.3 ± 16.0 | 70.1 ± 15.4 | 68.2 ± 20.1 | 0.51 |
1
Significance of difference (end of low-normal and high-normal pH phases) between means tested by paired t test and between medians by Wilcoxon's signed-rank test.
2
Mean ± SD (all such values).
3
Median; interquartile range in parentheses (all such values).
4
Mean of values for 7 study subjects; the skin of one subject each was too tight in the subscapular and midcalf areas to allow for measurement of skinfold thicknesses in that area.
