Cumulative hazard of deterioration event in patients who had no cardiac arrest within 24 h. DLA denotes deep-learning based artificial intelligence algorithm, ECG electrocardiography, and ICU intensive care unit. The cutoff point used for dividing the risk groups was selected when the overall sensitivity was 90% in the development dataset. Cox proportional hazards regression was used to estimate the hazard for the delayed cardiac arrest and the deterioration events
