Multiple regression of water turnover (L/day) as dependent variable and FFMI and VM/day as independent variables (n = 22)
| L/day | B | SE | β | P |
|---|---|---|---|---|
| Step 1 | ||||
| Constant | .650 | 1.408 | ||
| FFMI | .167 | .092 | .38 | NS |
| Step 2 | ||||
| Constant | -.699 | 1.294 | ||
| FFMI | .174 | .078 | .39 | <0.05 |
| VM/day | 1.580E-006 | .000 | .51 | <0.01 |
Note Step 1: R2 = .14 (p = NS), Step 2: R2 = .40 (p < 0.01), R2∆ from Step 1 = .26: L/day = liters per day, FFMI = Fat free mass index, VM/day = Vector magnitude counts per day, NS = not significant.
