Sequential organ failure assessment (SOFA) score without Glasgow Coma Scale (GCS) on day 1 was measured as the worst data within the first 24 h, excluding GCS score.

Model 1 included lymphocyte count on day 2, SOFA score on day 1, age and time from collapse to return of spontaneous circulation (ROSC), for which the P‐values were < 0.1. Model 2 included lymphocyte count on day 5, SOFA score on day 1, age and time from collapse to ROSC, for which the P‐values were < 0.1. Model 3 included lymphocyte count on day 6, SOFA score on day 1, age and time from collapse to ROSC, for which the P‐values were < 0.1.
