Maximum score				5

OR and CI with multivariable logistic regression analysis. CI: Confidence interval; OR: Odds ratio; ASA 3-4: American Society of Anaesthesiology of 3 and 4; ERCP: Endoscopic retrograde cholangiopancreatography; ASA: American Society of Anaesthesiology; pre-op ERCP: Pre-operative endoscopic retrograde cholangiopancreatography; Delayed surgery: Patients treated after a previous cholecystitis in a delayed setting; Maximum score: Delayed and acute cholecystitis exclude each other.
