From: Old subjects with sepsis in the emergency department: trend analysis of case fatality rate
Temporal trends in case fatality rate (CFR) in high- (upper panel) and low-risk (lower panel) patients aged ≥80 with sepsis related hospitalizations
Trends were tested by Poisson distribution analysis and represented by line graphs as mean with 95% confidence intervals in high-risk (full boxes) and low-risk (empty boxes) patients aged ≥80 with sepsis related hospitalizations.
