  1. Bold values for % increased mortality for weekend admissions denote large significant weekend mortality effects (>20%)
  2. Bold values for reduced admissions at weekends denote large reductions (>40%)
  3. Weekend mortality effects are based on odds ratios, obtained through multiple logistic regression modelling
