The RR of CRRT initiation
This study aimed to determine if FST, as an exposure factor, influences doctors' decisions to initiate CRRT. To do this, the relative risk (RR) of the FST not responding to the initiation of CRRT was established. Patients who were FST-nonresponsive were 2.379 times more likely to initiate CRRT than those who were FST-responsive (95% confidence interval [CI], 1.644–3.443,
