Pasquier 2018 HOPE survival probability after ECLS for hypothermic cardiac arres
Pasquier 2018 HOPE survival probability after ECLS for hypothermic cardiac arrest from sex (published male coefficient, not race), asphyxia, age, potassium, CPR duration, and temperature. Returns logit, estimated_survival_percent from the unrounded logit, and Table 2 HOPE >= 10% flag. Not an ECLS or rewarming order. magent does not cannulate.
