Note:
MEWS, modified early warning score. Model 1: MEWS; Model 2: Gender*Age + MEWS; Model 3: Age + MEWS; Model 4: Gender + eMEWS; Model 5: Age + Gender*Age + MEWS; Model 6: Age + Gender*Age + MEWS + Gender; Model 7: Age + Gender + MEWS; Model 8: Gender*Age + Gender + MEWS. Logistic regression models were developed against MEWS, age groups (‘1’ for 75 years old or above, and ‘0’ for 60–74 years old), gender (‘1’ for male and ‘0’ for female), and the interaction between age group and gender (age*gender).
