Description

I am currently using the MIMIC-IV derived sofa table for my research.

I noticed that about 40% of stay_ids have null values for the respiration and liver SOFA subscores across all timestamps.Clinically, it seems unusual for these SOFA subscores to be missing at such a high rate.

I would appreciate it if you could provide any insights into why these missing values might be occurring. Additionally, I would be grateful for any solutions or recommendations on how to handle these missing values.

Your work is fantastic and greatly appreciated.
Thanks for reading!
