Notes: £PRR compare the proportions between %length of stay (>5 day) and % length of stay (<5day) using Pearson’s chi-square test. ¥PRR compare the proportions between %invasive and %none-invasive using Pearson’s chi-square test. µ95% Confidence intervals (CI) which do not include 1.0 are statistically significant. *Statistically significant (CI do not include 1.0).
