Figure 1 Study sample selection
ESRD, end-stage renal disease, RRT, renal replacement therapy, SCr,
serum creatinine.
Figure 2
A median number of days of hospital care before and after detection of
HA-AKI
Days before AKI were calculated as the number of days from admission
until the AKI criteria were met for the first time. p-value 0.05 and
p<0.001 for differences between HA-AKI stages in the number of
days before and the number of days after AKI, respectively. HA-AKI,
hospital-acquired acute kidney injury
Figure 3 Cumulative hazard function curves comparing the length of stay,
the risk of in-hospital and 180-day mortality in No AKI and AKI patients
by AKI severity
When plotting hazard functions for the length of stay and the risk of
in-hospital mortality, discharge and death were considered to be the
competing risk outcomes. CA-AKI, community-acquired acute kidney injury;
HA-AKI, hospital-acquired acute kidney injury.
