2. Figure 1
Risk profiles by quintile of {clearance × time} (Kt), adjusted and not adjusted for the body size measures. The P values over the bars indicate the significance of the odds ratio compared with the appropriate reference group. The value over a single bar indicates that the P value was outside of the range indicated for the others in the quintile. Symbols are: (▪) none; () body mass index (BMI); () weight + height (wt + ht); () weight; () total body water (TBW); (□) body surface area (BSA).

3. Figure 2
Risk profiles for four of the five body size measures. Body weight for height is not shown (discussed in text). The P values over the bars indicate the significance of the odds ratio compared with the appropriate reference group. Symbols are: (▪) Kt not adjusted; () Kt adjusted.

4. Figure 3
Risk profiles for {clearance × time} for (A) males and (B) females. The risk profiles are shown not adjusted and also adjusted for the body size measures. No fewer than 10% of males or females were in any Kt group. The value over a single bar indicates that the P value was outside of the range indicated for the others in the quintile. Symbols are: (▪) none; () body mass index (BMI); () weight + height (wt + ht); () weight; () total body water (TBW); (□) body surface area (BSA).
