Notes: *KPI refers to key performance indicators. P ≤ 0.004 is considered significant using the Bonferroni correction. †Indicates that a KPI is expressed in percentages. §Rate per 10,000 patients. ¶Rate per 1000 Patients’ Days. ↑Indicates that the outcome improved whether it was an increase or a decrease. ↓Indicates that the outcome did not improve whether it was an increase or a decrease.
