What does it mean "patient K"? I googled it to find an answer, but I found a lot of results without explanation to this term. What is "patient K"?
Clinical Example: Patient K., 54 years old, during 15 years has been suffering from type II DM (Diabetes Mellitus) with periodic phenomena of decompensation... (Obesity and Diabetes Mellitus - Book)
Another one: "Fig. 1. Patient K. with arteriovenous macrofistulous dysplasia of facial soft tissues before surgery." (researchgate)
Now, I don't think it is just an ordinal letter as (A,B,C,....K etc.) since it appears in places in which there are 3-4 questions only without referring to other letters at all.
