Abbreviations: ROSC, return of spontaneous circulation; RTI, response time interval; STI, scene time interval; TTI, transport time interval; TPT, total prehospital time; EMS, emergency medical service. Time variables were reported as median and interquartile range and categorical variables as numbers and percentage. The p-values were calculated using the chi-squared test for categorical variables and Mann–Whitney U test were used for continuous variables.
