Figure 2.
Kaplan-Meier survival curves of (a) the patients discharged alive after an AKI episode (solid line) and of the population of São Paulo city (dashed line); (b) Comparison of the effect of age on survival in patients discharged alive after AKI and in the population of São Paulo city.
Solid lines represent the survival curves of AKI patients, and dashed lines represent the survival of the São Paulo population. Regular lines represent patients and population aged <65 years, and bold lines represent patients and population ≥65 years.
