Figure 1.

The Kaplan-Meier survival analysis is based on the total survival days in the period from hospitalization to discharge among patients with dengue fever (DF) or dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) in the renal failure (RF) group and in the non-RF group. Event of interest was defined as patient death during hospitalization and patient discharge as censored. There is overlapping of the curve in RF and non-RF groups of DF, but the patients with DHF/DSS in the RF group have significantly higher mortality than the others by log rank test (P < 0.001).
