I'm not sure what's a good replacement though. One question is: if we reduce 10 MB memory at startup, why didn't we also reduce 10 MB memory in the end? Is it that we just defer the memory allocation to a later point? I believe the original intention of measuring the startup me...

Our regression analysis in the derivation cohort demonstrated a final adjusted model that, in general, was almost similar to our original model, based on the complete cohort when comparing β‐values. However, despite almost identical β‐values 'Previous difficult tracheal intubation' was no longer...
