Blood chemistry changes after intervention in test group versus control group.
| Measure | Test | Control | All | P value |
|---|---|---|---|---|
| n (mean ± SD) | n (mean ± SD) | n (mean ± SD) | ||
| Osmolality (mOsm/kg) | ||||
| Baseline | 32 (300.3 ± 4.7) | 32 (298.8 ± 6.5) | 64 (299.5 ± 5.6) | |
| Study end | 31 (297.0 ± 2.8) | 31 (300.1 ± 4.1) | 62 (298.5 ± 3.8) | |
| Absolute raw change | 31 (−3.4 ± 5.4) | 31 (1.3 ± 7.7) | 62 (−1.0 ± 7.0) | |
| Adjusted mean change (SE) | −2.6 ± 0.6 | 0.5 ± 0.6 | 0.001 |
Values are shown for all subjects randomized and for whom data were available. SD, standard deviation; SE, standard error of the mean.
P value determined by analysis of covariance, adjusted for baseline values (parameter and cigarettes consumption).
