2. Figure 1
Relative risks of death (▪) and first hospitalization (Δ) by quintile of scores for each component of health-related quality of life (HRQOL), adjusted for all variables in Tables 1 and 2, including albumin, stratified by country and diabetes. The highest quintile is used as the reference group. For all six lines, there was a statistically significant trend (each P < 0.001) for the risks of both outcomes to increase with lower scores. (A) Physical component summary (PCS). (B) Mental component summary (MCS). (C) Kidney disease component summary (KDCS).

3. Figure 2
Adjusted relative risks of death (A) and first hospitalization (B) by quintile of scores for each component of health-related quality of life (HRQOL) and for albumin, using the highest quintile as the reference group. For all eight lines, there was a statistically significant trend (each P < 0.001, except for hospitalization and albumin, which were P < 0.05) for the risks of both outcomes to increase with lower scores. Abbreviations are: MCS, mental component summary; PCS, physical component summary; and KDCS, kidney disease component summary.
