Figure 4.
Forest plot of the incidence of sepsis. There was statistically significant higher incidence of sepsis in intensive care unit (ICU) compared with non-ICU nursing (fixed, RR, 4.23; CI 1.12 to 15.91, p=0.033, I2=0%). The horizontal lines indicate the 95% CI for the five included studies. The squares in the middle of the lines indicate the mean effect of the study. The diamond shape at the bottom indicates the 95% CI for the pooled effect.
