Diagnosis · The evidence behind it · Element

The strength

How well the evidence supports the diagnosis.

The part

What it is

Weak evidence for an important diagnosis is not a reason to abandon it. It is a reason to fund finding out more before committing the year.

Recording the strength keeps that decision available rather than implicit.

The attributes it carries

Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
